That's very strange because neither ExtUtils::Command nor File::Path
(which is what rm_rf() uses) call chdir().
Looking at Debian's patches to 5.8.4...
http://ftp.debian.org/debian/pool/main/p/perl/perl_5.8.4-8sarge5.diff.gz
I see they'd done extensive rework of File::Path which includes
attempting to chdir into the directory being deleted.
So I'd say your Perl is broke. To be sure, try this:
$ rmdir foo
$ mkdir foo
$ chmod 400 foo
$ ls -ld foo
dr-------- 2 schwern schwern 68 Oct 11 14:56 foo
$ perl -MFile::Path -wle 'rmtree "foo"'
$ ls -ld foo
ls: foo: No such file or directory
Debian reworked File::Path to close some potential security holes.
Those have been fixed upstream but after 5.8.4.

Log: Patch for CAN-2004-0452 by Jeroen van Wolffelaar.
The rmtree() function in the perl File::Path module would remove
directories in an insecure manner which could lead to the removal
of arbitrary files and directories via a symlink attack.
Branch: perl
! lib/File/Path.pm
Debian's Perl in testing (5.8.8-6.1) does not make any changes to
File::Path and should work fine. Upgrade perl to Debian's testing or
install your own.
http://www.us.debian.org/doc/manuals/apt-howto/ch-apt-get.en.html#s-default-version
explains how to do this without much fuss.
