A few weeks I hacked makepkg to add this very feature, I didn't took
time to test
it exhaustively nor to propose it to the authors.
As an attachment here is a diff against the makepkg found in pacman-3.4.1-1,
it adds the --freeze-deps flag that change the package versions to be exactly
the one on the build system.
I would be glad to see this feature used here, and then proposed to the authors
on the behalf of the Arch-Haskell team.
Best regards,
