Re: gfortran.

Steve,

I wouldn't worry it too much . . . it only happens on the particular  
distribution.  And the easy cure is to recompile with g77 - which  
also happens to be part of the install on the distribution.  I have  
yet to load RHEL v5, but will soon . . . and see if that version has  
the same issue.
