Ah! this option did the trick! Great! Thank you!

I see.

~$ ls -l /sw/lib/libtermcap.dylib
lrwxr-xr-x  1 root  wheel  26 Apr 12  2010 /sw/lib/libtermcap.dylib -> 
ncurses/libncurses.5.dylib
~$ ls -l /usr/lib/libtermcap.dylib
lrwxr-xr-x  1 root  wheel  20 Apr 12  2010 /usr/lib/libtermcap.dylib -> 
libncurses.5.4.dylib

I do not have the same kind of link in /usr/local/lib.

Wow. You made my day ;-)
