ok, I've been back into Slackware and tried again after removing some of the junk and I got much further in the compile this time, but still no success
This time I get the following error
/usr/lib/libgobject-2.0.so /usr/lib/libgmodule-2.0.so -ldl /usr/lib/libglib-2.0.so
/usr/lib/gcc-lib/i486-slackware-linux/3.2.3/../../../../i486-slackware-linux/bin/ld: cannot find -lslang
