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.
