cannot find -lX11

[Iain Morgan <Iain.Morgan%nasa.gov@localhost>]

Greetings,

I'm new to pkgsrc (I've only been playing around with it for a few days)
but I seem to have run into a problem with it on an x86_64 SLES 10
(Linux) system. From various searches, it looks like this problem has
cropped up before, but I haven't seen a solution.

For whatever reason, the build process does not seem to be correctly linking
against libX11.so. I note for example that ~/pkg/share/x11-links/ has lib/
directory containing symlinks to the systems's 32-bit libraries, but there isn't
a lib64 directory.

Replacing the symlinks in work/.buildlink/lib with ones pointing to the 64-bit
libraries and (for good measure) adding a link for libX11.so does the trick, but
I would think there should be a better way.

Is there anything I can add to the mk.conf (or some other file) to address this?
