The current version of Pd still uses oss for midi... sigh... is this on
FC3? Perhaps you are being bitten by the lack of default oss midi device
files in udev's configuration. Check to see if you have the device files
and you have permission to open them:

  ls -l /dev/midi*

If there are no device files do this:

  cd /dev
  ./MAKEDEV midi

that should create them. To make the change permanent (for now, I should
get a package that does this for you) copy those files to
/etc/udev/devices, they will be recreated on the next boot.
