PDFlib 4.01 on SCO Unix ????

Just a quickie, Anyone had any luck compiling PDFlib 4.0.1 on a SCO 5.0.x Box. I've had a quick play with different combinations and am using --with-pdflib=/usr/local in the PHP configure but no joy at the mo. Getting the 'Something must be broken' line. Error in debug.log: gcc -o conftest -g -O2 -DSUPPORT_UTF8 -L/usr/local/lib -L/usr/local/lib -L/usr /src/gd1.3 -L/usr/src/gd1.3 -L/usr/informix/lib -L/usr/informix/lib -L/usr/i nfor mix/lib/esql -L/usr/informix/lib/esql -L/usr/src/php-4.0.6/ext/informix -L/u sr/s rc/php-4.0.6/ext/informix conftest.c -lpdf -lz -lgd -lz -lcrypt -lm -ldl -lsocke t -lsocket 1>&5 dynamic linker : ./conftest : error opening libpdf.so1^M /usr/local/lib/libpdf.so1 does exist BTW. I'm very tired so could be missing something stupid but would appreciate any tips from people who have managed it already. Regards, - Paul -
