Description of problem:
when using "plugin capiplugin" to access ISDN modems, pppd crashs:
-----------------------------
Plugin userpass.so loaded.
userpass: $Revision: 1.5 $
Plugin capiplugin.so loaded.
capiplugin: $Revision: 1.36 $
capiconn:  1.13

-------------------------------

Version-Release number of selected component (if applicable):
ppp: 2.4.4
isdn4k-utils: 3.2-54.fc7

How reproducible:
100%

Steps to Reproduce:
1. configure a ppp peer with "plugin capiplugin.so"
2. start pppd

  
Actual results:
crash (see above)

Expected results:
no crash ;-)

Additional info:
The reason is a bug in isdn4k-utils package:

The capiplugin (/usr/lib/pppd/2.4.4/capiplugin.so from isdn4k-utils package)
tries to load libcapi20.so (most likely via dlopen). Unfortunately isdn4k-utils
does only include:
/usr/lib/libcapi20.so.3
/usr/lib/libcapi20.so.3.0.4 .
The required libcap20.so file is only available in the isdn4k-utils-devel package.

So there is a workaround: just install the devel package. ;-)

A short-term solution could be to put the *.so link into the isdn4k-utils
package itself.

If it would be better to let the capiplugin.so dlopen the the libcapi20 using
the long name (libcap20.so.3) or something like this I'm not 100% sure.

I'm setting the severity to high because it is (from a high level point of view)
a crash/segfault.
