Nice idea, but not the right answer. Well, at least not for ntop. Frankly,
FreeBSD should pick ONE as the default and put the symlink in, otherwise
every single package/port that refs libgd has to be tweaked. So it should
be libgd and libgd2 or vice versa.
The right (clean) answer inside ntop is to experiment with the LDFLAGS,
CPPFLAGS and other options and then put any OS specific stuff in
configureextra...
In configureextra, you get access to the flags at the very beginning,
meaning that what is already set is pretty minimal. The idea is to set
things before ntop goes looking, not to fix up what it finds. But still,
you can get pretty creative in these files, for example:
LDFLAGS="-lgd2 ${LDFLAGS}"
tells ntop to use gd2. You might want to put an if test in to make sure the
fool thing exists.
Or use the macro - look at the Solaris iconv line.
Look over the files - there's already examples of a lot of fixes there.
You might have to do the iconv-type stuff AND create the ln in the ntop work
directory, so that gcc can resolve -lgd, even though the -lgd2 you put at
the top takes precedence.
