First, it is not clear what compiler is f95. If it is gfortran, then
use the command
  f2py -m modulename -c --fcompiler=gnu95 tmpo.f

If it is something else, check the output of

  f2py -c --help-fcompiler

and use appropiate --fcompiler switch.

Second, I hope you realize that the first command has no effect to
the second command. If you have edited the tmpo.pyf file, then use
the following second command:

  f2py tmpo.pyf  -c --fcompiler=gnu95 tmpo.f

I don't  have ideas what is causing this import error. Try
the instructions above, may be it is due to some compile object
conflicts.
