[LON-CAPA-dev] Perl Module notes

[Matthew Brian Hall]

I just ran into this problem and found the solution.  I thought I'd pass
it along because others (Scott & Guy) are likely to run into it.

If, when compiling a perl module you get the error:

`sv_undef' undeclared

You need to re-make the makefile with a new parameter:

perl Makefile.PL POLLUTE=1

The reason this is needed is:

> 5.005_53 and later releases do not export unadorned
> global symbols anymore.
