I was building denemo against the modified portmidi package from my own build 
project https://build.opensuse.org/package/show/home:edogawa/portmidi .
My modification was old, so I don't remember which application had required 
that, probably denemo itself... anyway i did ln -s libportmidi.so 
%_libdir/libporttime.so and the same for static libraries.
Until yesterday this portmidi package got compiled only for openSUSE, therefore 
denemo's Fedora build tried to use the original Fedora portmidi package, and 
failed, not at configure time, but later when linking because somehow 
-lporttime had made it to the linker command, but there was no libporttime.so 
existing.

I'm not sure if one can assume for all platforms and distros that libporttime 
is gone and the stuff from porttime.h is handled by libportmidi.so. If so, I 
think -lporttime should vanish from the linker command, otherwise the 
configure.ac macro should be refined to not only check for the header, but find 
out how to construct the correct linker command.

But IMHO all that is superfluous work, for linux at least, and we should try to 
make auto-connecting to (remembered after first configuration) ALSA or JACK 
MIDI ports happen instead, if I understood Jeremiah and that's the only reason 
for using portmidi...
