Keep in mind that the result of the '(build-program ...)' is a program
that will be invoked as a separate program.  Exceptions do not
propagate accross process boundaries,  so 'build' cannot catch the
exceptions happening inside, so 'build' cannot catch the exceptions
happening inside 'build-program'.  Hence, the error handling bits need
to be inside the 'compute-guix-derivation'.

Greetings,
Maxime.
