Configured a test build using ./configure --prefix=/ccs/home/ayla/apps/graphviz --enable-python25=yes --enable-static=yes --enable-static --disable-shared --enable-shared=no --with-expat=yes.

Configure appears to work fine (I put an echo statement printing out the value of $EXPAT_LIBDIR, which gets set to /usr/lib64), but linking fails with the following error:
