How can you fix this in startup scripts?

Thanks, this probably does work, but I didn't check it for the reason
below (I'm on the daily digest mailings so I had sent mine before
reading your post)

I have standard installations of X11, Xcode, and gfortran 4.2.1 from
your site. I did upgrade my previous developer tools with the version
on the leopard dvd, possibly that is the cause? Either way, I figured
out that calling configure as:
configure --x-libraries='-L/usr/X11/lib' --x-includes='-I/usr/X11/include/X11'
X_LIBS=-L/usr/X11/lib
succeeds, and then the build can be completed with X11 support, and
the ability to build packages without specifying the PKG_LIBS variable
as you suggested.
To answer your other question, calling "configure" with no arguments
fails for inability to link the library Xt (from config.log:
configure:45035: gcc -std=gnu99 -o conftest -g -O2 -fPIC
-I/usr/local/include -no-cpp-precomp -L/usr/local/lib conftest.c -lXt
-lm -liconv >&5
ld: library not found for -lXt
collect2: ld returned 1 exit status
)
Anyway, I certainly didn't move around any of the X11 libs or headers
since installing them. Perhaps you have some symlinks or the X_LIBS
variable already set, either of which probably circumvent this
problem?
thanks again,
Dan
