By default octopus is installed in /opt/etsf/ [1] and normally this 
location requires root access to install, this why your installation fails 
with permission denied. You can specify a different instalation path 
using the 
--prefix argument of configure (if you change this value do not forget to 
do a make clean as the location is hardcoded in the binary).

[1] This location is common for all software packages that are part of the 
ETSF (http://www.etsf.eu). ETSF I/O is a library provided by the ETSF for 
input/output.

You can just install another version of OpenMPI compiled with gfortran, as 
long as you select a different path (and you use the right one) there 
shouldn't be any conflicts.
