I was able to install rmutil by using g77. During installation, R prints
out the gfortran command with parameters. I ran this part separately using
g77 in place of gfortran. I could have used a link to g77 (if I removed
gfortran) but when I did this, there was a problem with the
"mtune=pentium4" argument so I removed this argument. Then the various
fortran programs compiled. I then use R to install the package and
(miracuously) R installed the package. (It seems R skipped trying to
compile the fortan code once the executables were already created and
available - so R was able to put the created functions into the library
tree so they could be used in an R session.)

This is all very kludgy - I would prefer to go back to a few days ago
without gfortran and R packages installed without any problems.
