I don't think there is an existing solution but you should check on the module-build list to be sure.

If I were in in your corner, I would go with 5 (1 + 2 = 5), and keep it perl, something like 

% perl build-dist1.pl
creating dist1tempdir
chdir dist1tempdir
copying defaults (README INSTALL LICENSE...)
creating MANIFEST
copying files
creating Module::Build object (like in Build.PL)
dispatch build
dispatch test
dispatch dist
created dist1-0.01.tar.gz successfully
destroying Module::Build object
uploading dist1-0.01.tar.gz
chdir ..
cleaning up dist1tempdir
done!
