This makes sense assuming that we have no libmp right now. That assumption is false. Observe: dima@hornet% ll /usr/lib/libmp* -r--r--r-- 1 root wheel 82274 Jul 13 01:51 /usr/lib/libmp.a lrwxr-xr-x 1 root wheel 10 Jul 13 01:51 /usr/lib/libmp.so -> libmp.so.3 -r--r--r-- 1 root wheel 39948 Jul 13 01:51 /usr/lib/libmp.so.3 All programs that need a libmp interface are linked as "-lmp -lgmp". I'm guessing that /usr/lib/libmp.so that we have now is a libmp interface in terms of libgmp.
