hi :-) what does exactly port install libtool ? while making a tool, i got the error /usr/bin/libtool: unknown option character `m' in: -macosx_version_min on the list GNAT-OSX@hermes.gwu.edu, someone said me "It looks like it is using the wrong libtool. Apple has its own. If there is a libtool in the path that isn't the Apple version then you will have problems creating dynamic libraries." but thomas% which libtool /usr/bin/libtool so it seems to be the apple's one and after have run "port install libtool", it's the same(the error and the path), and there is no libtool binary in the bin folder of macports so, what should i do ? ps : how to know the version of the installed libtool ? -- Mon CV : http://tDeContes.hd.free.fr/divers/emploi/
