Newbie compile error help

I'm trying to make a gradekeeper program using Xcode Tools that has
been compiled successfully many times on both Solaris and Linux using
their default compilers, but getting a slew of error messages.

I'm using gcc from one of the most recent Xcode Tools distributions,
powerpc-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5465).

The output of the make is shown below. What's up with this
$non_lazy_ptr in lib.a(histo.o) business, and more importantly, how do
I fix it?

TIA, Vince.

With errors like,

Undefined symbols:
?"_pscore", referenced from:

in the ld command (link stage),

ld: symbol(s) not found
collect2: ld returned 1 exit status

It looks like you are missing object module(s) or library(ies). ld
cannot find those symbols it is complaining about. Maybe look at the
successful package on Solaris or Linux and compare to the Mac package to
see what is missing. You could also search the code for the symbol
names to see what might be missing.
