Thank you again Jim, following your indications I solved it (btw, this 
use of proc is just like lamda, right?)

This is the new rule:
# Rule to compile main objects from source.
rule %r{^mains/.*\.o$} => [
  proc { |fn| fn.sub(%r{^mains/}, '').ext('bas') },
  proc { |fn| File.dirname(fn) }
] do |t|
  sh "fbc -c #{t.source} -o #{t.name} -m #{File.basename(t.source).ext}"
end

Guess could be solved more "elegant", but it works :-)

I added a directory task into fb_project to intelligently add when is 
needed (mains/other or leave just mains)

Thank you for your time (again).

Regards,

Luis
