I'm not sure if it's a problem with the portfiles or if it's a problem with code in base/ but I'm running into trouble trying to install +devel variants of various ports (auctex, slime, haskell-mode.el, etc). I'm using a subversion checkout of the trunk; everytime I try to install one of these +devel variants I get an error message like: Error: Error executing devel: can't set "depends_lib": invalid depspec: Error: Status 1 encountered during processing. I haven't checked all of them but it seems like any port that does something like variant devel { depends_lib-delete port:emacs depends_lib-append port:emacs-devel } will run into the same error. I can file a bug report in Trac, but I was wondering first whether someone else is seeing this problem, and whether I should file it against the specific ports or against base. Thanks, Martin
