Hi Bob and welcome to the world of crap.

Seriously and honestly, the FreeBSD porters made a big bad pile of crap
when they some years ago decided to name "gtk-12" and others as "gtk12".

Then they added to this pile of crap by renaming it back sometime after
6.0 release.

Long story short, it's not our fault.

Btw. fpc 2.0.2 is in ports now.

You need to symlink those libraries or patch manualy, but we can't
change it to the new ones since anyone with FreeBSD 6.0 or older (if
they didn't portupgrade) won't work then.

FPC 2.0.4 will have a new mechanism of "libalias" which will enable us
to fix this by just adding either command line params (eg: fpc
-Laglib=glib-12.so) or changing it in fpc.cfg for all compilations
(preffered and porters can do this)

Welcome to the world of shit.. eh sorry I ment unix.

It was written in C what would you expect?
