I use gdal on SL6 not SL7, don't use python much and pip not at all,
but I'll ty to help.

Where did you get gdal from -
 	rpmquery -i gdal
might say, if you don't know.

The cpl_port.h missing error suggests that pip assumes
you already have gdal installed (in the place it is looking
and probably the expected version).
Since you do have gdalinfo installed I guess that pip isn't
looking for cpl_port.h in the right place; mine is at
   /usr/include/gdal/cpl_port.h
but I think from the exact error below that pip expects it at
   /usr/include/cpl_port.h
while there various ways of hacking a solution to this
specific error, I'd expect they would only lead to
the real issue causing more errors.

My guess that you have installed gdal from epel,
but not the gdal-python package that goes with it.
Could you try

 	sudo yum --enablerepo=epel install gdal-python
?
