Does your $PATH exist and include /usr/bin ?  The install of
gcc-2.95.3 must have access to a C compiler of some sort.

Are you root at this point?  You may have to be to do these things in
/usr/local/bin.

     Your install of aips cannot use 2.95.3 unless you get it
installed.  I have never encountered a problem doing that but I stick
compilers in some private place and then try to figure out where the
gcc and g77 executables have actually ended up.

     Perhaps Pat Murphy will have an idea - he does not work for aips
any more but knows a lot more than I do about these matters.

     This has to point at your 2.95.3

     This has to point at your 2.95.3

I wish it made more sense - keep trying and let me know hat you
find...
