please "help yourself". Compilation problems, especially weird  
problems like yours,
are often due to something strange in a specific machine. Sometimes  
expert eyes
can immediately detect what is wrong, sometimes the origin of the  
problem is not
obvious. In the latter case only the owner of the machine can find  
out what is wrong
by carefully looking at the error message and by trial and error.

and nothing else? look for suspicious warnings and messages

iotk_base.f90 is compiled...

...module iotk_base is not found. Are there iotk/src/iotk_base.o and  
files (or .d, or .whatever your compiler uses)? If not, there is  
something wrong with
your compiler or your mpif90 and you should try to understand why it  
doesn't produce
an object file. If yes, you should try to understand why it doesn't  
locate a module,
since options -I are correct
