Status changed from New to Validated

We shouldn't overlink because it can create problems for other platforms.

We created some helpers to check if a lib is using a symbol and if a lib is already linked to another one, we should use/fix them to be sure all checks are made.

If you have undefined symbols when linking, you could paste errors there and we can find what lib is missing :)

otool is working fine under Mac OS 10.5 but apparently that's not the case under Mac OS 10.6, so I replaced otool by nm to check symbols.

Ok here is the list of missing symbols and libs containing the symbols which i had to set to REQUIRED to make ryzom_client run on 10.6 with macport's libwww:

_HTGuess_new referenced from /opt/local/lib/libwwwapp.dylib (is in libwwwstream.dylib)
_HTLoadFTP referenced from /opt/local/lib/libwwwapp.dylib (is in libwwwftp.dylib)
_HTLoadGopher referenced from /opt/local/lib/libwwwapp.dylib (is in libwwwgopher.dylib)
_HTLoadNews referenced from /opt/local/lib/libwwwapp.dylib (is in libwwwnews.dylib)
_HTLoadTelnet referenced from /opt/local/lib/libwwwapp.dylib (is in libwwwtelnet.dylib)
_HTXML_new referenced from /opt/local/lib/libwwwapp.dylib (is in libwwwxml.dylib)
_HTZLib_inflate referenced from /opt/local/lib/libwwwapp.dylib (is in libwwwzip.dylib)

btw, i updated to r1049 before creating the list :)

Maybe it is worth mentioning that some part of the under link detection seems to work well:

-- Underlinking found: /opt/local/lib/libwwwapp.dylib needs 
          /opt/local/lib/libwwwcache.dylib but is not linked to, manually linking...
-- Linking with /opt/local/lib/libwwwcache.dylib
