Try this:

Go back to your default build: the one that ended up with only linker 
errors.  Go ahead and build: you'll fail at link time on the applications.

Just for grins, manually run the first failed link command line adding the 
libraries into the command.  For example, if it were:

gcc .... -o gdal_warp ... -lstd++ -lm -l...etc.

change it to

gcc .... -o gdal_warp ... /usr/local/lib/libstdc++.so.4 
/usr/local/lib/libstdc++.so.5 -lm -l...etc.

And report back how it goes.  That's how I started.  If you want to take 
this offline, you can send this to me: perhaps I can help.
