Buildsys glitch?

[Jonathan Underwood]

Hi,

I just pushed builds for an updated emacs-auctex package for FC-4,
FC-5 and devel. FC-4 and devel succeeded (specs are the same), but
FC-5 fails during configure with this:

checking for emacs... /usr/bin/emacs
checking if /usr/bin/emacs is XEmacs... cat: ./conftest-478: No such
file or directory
configure: error: Unable to run /usr/bin/emacs!  Aborting!
error: Bad exit status from /var/tmp/rpm-tmp.55095 (%build)

which seems like a build system issue - emacs is in the BuildRequires
and is clearly installed? The same package builds for me locally on
FC-5, but I haven't had the time to do a mock build yet as the machine
I usually use for that is offline due to a power outage at work.

Any ideas?

Jonathan
