Description of problem:

Currently, only gmime versions 2.2 and 2.5 are available in Fedora:

$ rpm -qa gmime gmime22
gmime-2.5.1-1.fc13.x86_64
gmime22-2.2.25-1.fc13.x86_64

Version 2.2 has been superseded by 2.4 in 2008. And 2.5 is an unstable development branch, as evidenced by the lack of any release information on the gmime website [1]. This causes build problems with users of gmime, such as for example notmuch [2], which is currently stuck at version 0.5 in Fedora because newer versions require notmuch 2.4 but are incompatible with 2.5 [3].

Steps to Reproduce:

$ git clone git://notmuchmail.org/git/notmuch
$ (cd notmuch; ./configure; make)
[...]
notmuch-reply.c: In function ‘notmuch_reply_command’:
notmuch-reply.c:613: error: ‘GMimeSession’ undeclared (first use in this function)
notmuch-reply.c:613: error: (Each undeclared identifier is reported only once
notmuch-reply.c:613: error: for each function it appears in.)

GMimeSession has been removed in gmime 2.5, and if I understand correctly a backwards compatible alternative is not available.

Version 2.4 should therefore be the default in Fedora until the next stable release of gmime. Version 2.5 should be made optional or not provided at all.
