 Currently the Fedora RPM uses:

 sed -i "s/VERSION=%{version}/VERSION=%{version}-%{release}/g" configure

 This makes a version like "2.2.2-1.fc8" to be displayed in the Help >
 About and pidgin -d boxes.  These are very useful in user support in cases
 like:
  * Call in Help Desk where users are very inexperienced.  The support
 person can ask for Help > About and to read the version there.
  * pidgin -d output gives the exact package version, that also denotes the
 distribution of the user.  This might be useful for bug reports containing
 pidgin -d output.

 The above text replacement works fairly well, however it would be safer if
 a future pidgin version added a switch to configure to make this more
 robust.

 ./configure --extra-version="1.fc8"

 Displayed Version Before: '''2.2.2'''

 Displayed Version After:  '''2.2.2-1.fc8'''

 Another benefit of this is that pidgin can separate the upstream version
 from displayed version.  This may or may not be useful.
