Not knowing why you'd want to do this, or what obstacles you have in mind,
it seems there should be no trouble as long as you substitute
link-compatible compilers. Don't PGI 6.0 compilers work the same as
earlier ones? Build and install lam with your CC and CXX set to aliases
for gcc and g++, then change those aliases to point to pgcc and pgCC, or
some other compiler.
supposing you use bash
alias ccom=gcc
alias cxxcom=g++
alias fortcom=pgf90
../configure --with-cc=ccom --with-cxx=cxxcom --with-fc=fortcom
make....
later, change the aliases as you wish, at your own risk, keeping PATH and
LD_LIBRARY_PATH and options supplied consistent with the compiler in use.
g77, if it worked, would require -fno-second-underscore.
