This is about installing pidgin 2.7.9_0 from MacPorts to Snow Leopard on May 7th 2011:
automakefrom Macports will be used.
PATH=/opt/local/bin:$PATH /opt/local/bin/port install pidgin +quartz +no_x11
It will run into errors as some diff files do not fit any more. You can remove all patch related entries from
/opt/local/var/macports/sources/rsync.macports.org/release/ports/net/pidgin/Portfile and rerun the install command.
