environment modules for gcc/gfortran?

[Paul Richard Thomas]

Dear Katherine and Tom,

I believe that I have RHEL5.4 as a virtual machine at home.  If so,
I'll build a release version of 4.7.0 on it.  It'll take a few days
because I know that some of the dependencies will need updating and
all the usual good stuff.  I have to say that, whilst I am a gfortran
maintainer and would say this :-), building your own is very straight
forward on linices - just read the instructions at gcc.gnu.org and
follow them to the letter!

Not only does 4.7.0 do good things with typebound procedures but its
implementation of object oriented programming is sufficiently complete
that it deals with all the examples in Damian Rouson's book and he is
intending to use it for teaching purposes.

Best regards

Paul
