rpm-spec-mode uses replace-in-string which only exists in xemacs and not in standard GNU Emacs which prevents you from using the package building bits of rpm-spec-mode. rpm-spec-mode should either only be installed to work with xemacs or be fixed (I had tried an older version of rpm-spec-mode at one point before it made it into the package and it worked fine)
Verified. I mainlu use it for C-c e and C-c r, and hadn't noticed. Emacs 21 has "replace-regexp-in-string", not quite sure what to use for Emacs 20. I've notified the author.
It's fixed in 0.11e, available from http://www.tihlde.org/~stigb/rpm-spec-mode.el I've put together a emacs-20.7-33, which isn't yet in the tree.
It is now.
Looks good; thanks
