Problem building Pidgin.

[Konstantin Kharlamov]

Btw, it might help if you say what exactly are you trying to achieve. You see,
if for example you just want to work on some Pidgin plugin, then I don't think
you need to compile libpurple either. Simply installing Pidgin from installation
binaries for your system should give you libpurple.
