Port problems (XFree86-4)

[Adam K Kirchhoff]

Don't know if this is DragonFlyBSD specific, but XFree86-4 won't build
any more:

/usr/libexec/elf/ld: cannot find -lXThrStub

This used to be an issue for FreeBSD, but they fixed it at some point.
I don't know if changing the name is the cause of this problem, but I
might poke around the port some. 

Unfortunately, installing it via the packages is failing since pkg_add
is expecting a tgz file and the FreeBSD ftp server is now using tbz
files :-)
