The above message contained the following:

Happy nwe year to you, too.

But see below.

I don't like the last warning above.  The reason for the failure is in
the "config.log" file:

> configure:1608: checking user-defined Fortran-90 compiler "xlf95"
> configure:1615: xlf95 -c  conftest.f90
> xlf95: 1501-218 file conftest.f90 contains an incorrect file suffix

Apparently, the F90FLAGS environment variable should have contained
the "-qsuffix=f=f90" option before the configure script was executed.
If you need the Fortran-90 interface, then you'll have to rebuild the
package with this fix.

...

This is strange.  After preprocessing by the C preprocessor, the file
"test_get.F" is conforming Fortran-77 code and should be compilable.
The configure script determined that the xlf95 compiler correctly
preprocesses *.F files.

Because the command is so simple (xlf95 -c test_get.F) I suggest that
you drop into that directory and try to the figure-out what options are
necessary in order to get the xlf95 compiler to compile that file.

Let me know what you discover.
