The compile_et program installed as a part of the
e2fsprogs-devel package doesn't actually work. In
particular, if you try to compile Cyrus imapd (1.5.14 or
1.5.19) with this package installed, you get the following
after configure has run:
compile_et: Couldn't find compile_et's template files.
Apparently this is because "prefix" is not being set by
compile_et, so it's looking in /share instead of /usr/share.
Should be fixed in the public beta
