[R] (not) compiling fortran -- dynamic loading problem

Hi, everyone. This may be properly a fortran question rather than an R
question.
I'm trying to add a few print statements to otherwise working fortran code
in one of the libraries so I can see what's going on in the code. I have
no problem doing so on an SGI machine, but under LinuxPPC I've run into a
problem. The code compiles and creates a shared object (.so), but when I
issue the "library" command to load the new (printing) version, I get the
following error:
undefined symbol: do_lio
I assume this must be some fortran i/o function, and perhaps I'm missing a
library. But I've never seen this symbol before, and I can't find it in
the info pages for g77 (or on the LinuxPPC mailing lists). Does anyone
have any idea where I can find this library on LinuxPPC?
(Or do I have the wrong idea about what the problem is?)
Thanks,
Matt Wiener
