Dear Fabrice,

you need to use the workaround which is posted on PG website
(http://www.pgroup.com/faq/link.htm#link1a, FAQ: How do I fix a
": undefined reference to `f__xargc'" problem?) to link object files
which were previously compiled by pgf77 and g77.
The explanation and the contents of farg.f is posted there:
       integer function mpir_iargc()
       mpir_iargc = iargc()
       return
       end
       subroutine mpir_getarg( i, s )
       integer i
       character*(*) s
       call getarg(i,s)
       return
       end

Hope this helps,
-Viktor
