Ok so how do I tell the linkere where to look? I assume the same way I told it where to find libcurl with export LDFLAGS="-L/g/programming/libs/libcurl-7.16.4/lib" but if I make another export LDFLAGS line then it will over write the first one wont it? and export LDFLAGS="-L/g/programming/libs/libcurl-7.16.4 /lib:/g/programming/libs/zlib123/lib" doesnt seem to work.
