No. This is a completely new, and clean installation of FreeBSD 4.9R-p3.
Yesterday I downloaded 4.9R too, and upgraded to STABLE. When I installed
Perl 5.8.2_5 then, everything went fine.

Today, I changed my mind about STABLE, and decided I feel safer running a
RELEASE version; so I scrubbed the disk again, installed a new 4.9R, and
CVSup-ed to 4.9R-p3. Then I tried to install Perl 5.8.2_5 again; but, this
time, it failed.

There are only two things different since yesterday;

1): I commented out MATH_EMULATE; that potential reason you just eliminated.

2): I no longer run STABLE, but 4.9R-p3.

No. I am not enough of a C wizard to mess with such settings. :) I just ran:

    make PREFIX=/usr/local/perl-threaded WITH_THREADS

Here is the result:

asarian-host# /usr/local/perl-threaded/bin/perl -V:cc
cc='cc';
asarian-host# /usr/local/perl-threaded/bin/perl -V:gccversion
gccversion='2.95.4 20020320 [FreeBSD]';
asarian-host# /usr/local/perl-threaded/bin/perl -V:optimize
optimize='-O -pipe ';
asarian-host#

Thanks,
