That's a symbol from the Fortran I/O code.  There is no problem on RH6.0
on R 1.0.1, where the symbol is resolved from libg2c.a.

(1) Does FLIBS in etc/Makeconf include -lg2c?

(2) If so, do those packages have Makefiles in src? If so delete them
and reinstall.  (The latest version of akima does not, but earlier versions
did.)

(3) Does lg2c include e_wsfe?  (nm -g on it).  Is it finding the right
libg2c.a?

(4) I get nm -g ..../akima.so  giving

00013c5c T e_wsfe

and so I think it should be resolved in the *.so.

Which version of RedHat?  I suspect a RedHat inconsistency here, and other
people have reported that upgrading to the gcc-2.95.2 compiler set
solved the problem.  But it might just be old package versions.
