LD2, thanks for the post. After reading through the links you posted and then further testing, here's the first little interesting thing I found:

perl -MO=Bytecode,-omyfile.bc myfile.pl produces the bytecode file, as before

perlcc -b -o myfile.bc myfile.pl produces the bytecode, and automatically sticks in the perl header and use Byteloader 0.03; statement. The only problem was the perl header pointed to /perl instead of /usr/bin/perl, so I had to go in and edit anyway. But at least now I know that I was using the ByteLoader module correctly, since that was the way that perlcc sets it up.

Thanks for the filehandle links too. I'm trying to experiment with byteloader_fh() again, but I'm getting "Undefined subroutine B::byteload_fh" errors. I reloaded the B modules....I just found out that you can't reload the B modules without reloading all of perl....
