Build Liferea against Firefox instead of Mozilla

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5)
Description of problem:
Installation of the rpm fails asking for the following files:
error: Failed dependencies:
libgtkembedmoz.so is needed by liferea-0.6.4-1.b.i386
libxpcom.so is needed by liferea-0.6.4-1.b.i386
To resolve dependency, yum chooses to suggest installation of Mozilla.
This is an FC3 installation that is using Firefox. Both files could
already be found in /usr/lib/firefox-1.0/ directory. Why require
installation of mozilla 1.7.3?
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install fresh FC3 with only firefox 1.0, not mozilla...
2. Download rpm from Fedora Pre-Extras
3. rpm -ivh liferea-0.6.4-1.b.i386.rpm
Actual Results: Installation fails, with missing dependencies....
Expected Results: Package should install... :-)
The main reason were using Mozilla to build the Mozilla plugin, is
because we're tracking the upstream package. In addition, I'm not
even sure that there is a firefox-devel package to build against
currently in FC3.

Because actually the gecko runtime environment is only provided by the
$ rpm --redhatprovides libgtkembedmoz.so libxpcom.so
A few other packages also depend on it:
$ rpm --redhatrequires libgtkembedmoz.so libxpcom.so
Currently, the only way out would be to split off a liferea-mozilla
package for just the 15K small gecko/mozilla rendering plugin. Not
worthwhile for FC3. But could be reconsidered for FC4 if nothing
changes with regard to the gecko provider (we build against
Is it perhaps a change in the packaging of firefox-1.0 that I am
requesting then? To have the package admit that it is
installing/providing those particular files? What I mean is, I only
have firefox installed at the moment, and those particular files being
requested can both be found in /usr/lib/firefox-1.0/. What I am
apparently being dense about, is why can't liferea and the others like
epiphany simply be happy with what firefox is providing? I guess I am
not understanding the statements of building against mozilla-devel,
perhaps. Thanks for your patience.
Yes, what you have in mind is not available [yet].
The Gecko engine is only provided by the mozilla packages. Hence we
build against 'mozilla-devel', and the automatic dependencies are
satisfied by the 'mozilla' package. The firefox packages as found in
Fedora Core do not supply Gecko development files (no firefox-devel
package) and neither the Gecko Runtime Environment as shown in comment 2.
Btw, I've talked to Dag Wieers, who also provides a liferea package,
and he is not fond of a liferea-mozilla split-off either. Means we
will very likely release the 0.9.0b update as found in Fedora Extras
Wasn't there talk awhile back, about Mozilla separating the libraries
into a serarate package like libmozilla? I vaguely remember reading
something about it last year, but since I don't keep a close eye on
Mozilla developement I not 100% sure.
Here's a further update on library separation:
Looks like there is a firefox-devel package in Rawhide now, so once FC6T2 comes
out and I get it installed, I'll start building liferea against that.
Liferea is being built against firefox as of version 1.0.19 in devel.
