Re: Gnome won't compile: cannot find -lpcre

[Stephane Russell <stephane.russell@xxxxxxxxxxxxxxx>]

I looked at glib2 after your post, and I could see that pcre is not a
dependecy of glib2 because glib2 provides it's own. But it's not
intalling it (it's not in it's PLIST), so it's not in it's buildlink
either. Mystery solved. ;-)

Thanks for the help.
