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.
