Hooray, I got amarok 1.4 compiled and installed on FreeBSD 6.1.
To make it work I had to disable XMMS stuff and the MusicBrainz bits, but I don’t use XMMS and MusicBrainz isn’t too important to me.
If you want to make it work, you need to:
./configure --prefix=/usr/local --without-xmms --without-musicbrainz
Then:
rm libtool && ln -s /usr/local/bin/libtool .
Then:
gmake
And cross fingers.
Once it’s compiled successfully (I hope), then just
sudo gmake install
I did this without pkg_delete’ing my amarok 1.3.9 install and it doesn’t seem too upset – although it will complain about mismatched checksums when I do, I’m sure. Hopefully the time I do that will be to upgrade to 1.4 in ports though.

“sudo gmail install”
I assume that’s a typo and that you were thinking about the lovelyness that is gmail, rather than the gmake command you probably meant ;)
No, that’s the awesome power of gmail!*
(* Yes, whoops)
