As the quilt maintainer I was surprised to see Landry mention quilt on icb as a port that depends on procmail; I didn't even realize that quilt used procmail behind the scenes. :)
Turns out, quilt really only uses formail, and only to extract the value of headers. Reading RFC 2822 I think we can safely do this with sed, instead. (Well, technically gsed in this case; in fact, testing this exposed a few issues in our sed that I will investigate separately) I'd really appreciate some extra eyeballs on this new patch. quilt's mail regress test looks pretty thorough and it still passes, and I also manually verified the sed output matches formail's output. Cc'ing guenther@ in case he's got a spare minute or two to look this over and chime in. Once this goes in I'll push the patch upstream. Ok?
