Thanks for looking into this.

Yes, if I remove the "-lX11" from the configure-generated
"lavtools/Makefile" manually then everything compiles fine for me.

On the face of it, your "if HAVE_X11" would be a good fix for me - the
Gentoo ebuild will pass the "--without-x" or "--with-x" to configure as
appropriate, if that ultimately translates to the HAVE_X11 symbol. I'm
not too familiar with the automake/autoconf magic to work out quite how
it gets from end to end yet.

If you can suggest a patch to that Makefile.am file I can give it a go
and let you know.
