>Description:
if PKG_OPTIONS.libpurple+=perl _and_ a perl plugin installed
(f.i. wip/pidgin-twitterstatus) we get:

/usr/pkg/lib/purple-2//perl/auto/Purple/Purple.so: Undefined PLT symbol 
"purple_perl_callXS" (symnum = 610)

(this won't show if no perl plugin installed.)
>How-To-Repeat:
echo 'PKG_OPTIONS.libpurple+=perl'>>/etc/mk.conf
cd chat/pidgin && make install
cd wip/pidgin-twitterstatus && make install
pidgin
