I'm unsure what "downloaded also the package from the GDAL website"
means. If you activated the repo at
http://elgis.argeo.org/repos/6/elgis/x86_64/, by setting up a .repo
file the way the describe, cool. There are older versions available
from EPEL, and there's even a well organized postgis repository
described at http://postgis.net/install/ that also keeps gdal
up-to-date.

It suggests to *me* that Roxana has installed the gdal package, but
not the gdal-devel package that includes header files for compiling
gdal related software.
Roxana? If you have the yum repo set up, how about doing "yum install
gdal-devel" and trying again? Or given that the error was pretty
specific, you about "yum install /usr/include//cpal_port.h" ?
There is also a fabulous website at http://rpm.pbone.net/ for finding
out what RPM has a file that you're unsure of, or what third party
repository might have a newer version of a package If I look for
"cpl_port.h" on RHEL 6, CentOS 6, and Scientific Linux 6 on that web
site, I see it in the "gdal-devel" package from lots of places. That
site is also quite useful for finding python modules, since the names
of python modules RPM's can be fairly unpredictable.
Roxana or Andrew, if you'd like my patented rant about the dangers of
using "pip install" instead of finding or building RPM's for Python
modules, ask. It's a more complex and opinionated issue for me, and I
won't burden you with it right now.
