Apache::Peek and perl 5.8.0

Does anyone have Apache::Peek working with perl 5.8.0?  I can't get it to
build, and I can't find the symbols it's (apparently) missing anywhere in
perl 5.8.0's header files.  Example:

---

  CPAN.pm: Going to build D/DO/DOUGM/Apache-Peek-0.9501.tar.gz

Checking if your kit is complete...
Looks good
Writing Makefile for Apache::Peek
cp Peek.pm blib/lib/Apache/Peek.pm
/usr/local/bin/perl /Library/Perl/ExtUtils/xsubpp  -typemap
/Library/Perl/ExtUtils/typemap  Peek.xs > Peek.xsc && mv Peek.xsc Peek.c
Please specify prototyping behavior for Peek.xs (see perlxs manual)

Peek.xs: In function `DumpOP':
Peek.xs:316: `GVOP' undeclared (first use in this function)
Peek.xs:316: (Each undeclared identifier is reported only once
Peek.xs:316: for each function it appears in.)
Peek.xs:316: parse error before ')' token
Peek.xs:318: parse error before ')' token

...and so on.  Anyway, I can't even find "GVOP" in
/Library/Perl/darwin/CORE/*.h, which makes me wonder if it's just plain
incompatible with 5.8.0 (the docs don't seem to mention anything about it)
