Did you also set FFLAGS? Did you read and follow the example in the
R-admin manual. I assume the latter as the INSTALL file asks you to read
that manual.

I see no sign of 64-bit libraries (sparcv9) in there.

(that's OK, as none is needed.)

No, yes. If is saying it cannot run mixed Fortran and C code.
Please do look in the config.log file for the details, as it says (and
*please* do so before posting, as we cannot read the file for you).
When I saw this it was because the 64-bit shared libraries
(/usr/local/lib/sparcv9?) were not in my LD_LIBRARY_PATH. But I believe
you have not set up your compilers compatibly, and that you did not read
the manual as requested.
