        using gcc : custom : /home/amosa/bin ;

This assumes you actually used --prefix=/home/amosa (which seems like not
a very good idea, due a pile of random stuff dumped right in your home).

The errors you hint on (but without any details), suggest your compiler
is not really installed properly or correctly. Usually, after installing
a compiler to a custom prefix, it just works. For the binaries to work,
you'd have to use LD_LIBRARY_PATH.
