Well, you could also take a peek at net/cvsup-bin
Another binary used a lot. It might give some ideas.

*nod*
That could be a solution. Although it requires a clue.
Normally one does:
make
make install
make clean
What could be a solution would be to make and after the make go
interactive and ask to try to bootstrap from C or use the GHC-binary.
print/apsfilter is a good example of interactive stuff...

These are just some random thoughts. Surely I am missing some pitfalls,
but these might spark some ideas.
