Log Message:
Change PKGNAME from lablgtk to lablgtk2.
This way the package can be installed at the same time as x11/lablgtk
(their PLISTs do not conflict), and as additional bonus, the PKGNAME
matches the directory name.

No dependencies, so no dependency PKGREVISION bumps needed.

XXX: I don't think I can record this change in doc/CHANGES, can I?
