Sorry, I was a bit sparing with details. Early in the morning, and all
Many thanks for the swift reply!

Hardware: 700+ machines are 800 MHz Pentium III, 1 GB RAM, Red Hat 7.2
168 machines are dual 2.8 GHz Xeon, 4 GB RAM, Red Hat 8.0
I'm compiling on the older machines to make sure there won't be library
The compiler versions are:
Intel(R) C++ Compiler for 32-bit applications, Version 8.0 Build
20031016Z Package ID: l_cc_p_8.0.055
Intel(R) Fortran Compiler for 32-bit applications, Version 8.0 Build
20040412Z Package ID: l_fc_pc_8.

So 12 hours is bit excessive. :-) At least now I know. Thanks!

Ah. This is indeed 1.9.0, since that is what was asked for.

With 1.9.0, I never get an output file. On interrupting the make
check, it says:
make: *** Deleting file `base-Ex.Rout'
and hangs again. I have to background it and kill it.
The same thing happens with 1.9.1. I think I'll use gcc/g77 as
suggested by others to get a working install for now, and then I will
look into a better optimised version at a more leisurely pace.
