Hello Iris.  My response is inline.

Does libibumad.so exist?  If the link does not exist please create it by
something like:
    ln -s /usr/lib64/libibumad.so.1.0.3 /usr/lib64/libibumad.so

I've seen this behavior before where if the ofed installation is
incomplete the required libibumad.so (and others) link was not created.

If this is the case then you should be able to configure by simply using
./configure without specifying any of the extra options.
