The Makefile directed me to /usr/lib/perl/5.6.1/Config.pm, which helps
explain what's going on here.  It contains lines like:

installsitearch='/var/tmp/hhl-target-perl-ppc_82xx-root/opt/hardhat/devkit/p
pc/82xx/target/usr/local/lib/perl/5.6.1'
installsitebin='/var/tmp/hhl-target-perl-ppc_82xx-root/opt/hardhat/devkit/pp
c/82xx/target/usr/bin'
installsitelib='/var/tmp/hhl-target-perl-ppc_82xx-root/opt/hardhat/devkit/pp
c/82xx/target/usr/local/share/perl/5.6.1'

and corresponding lines like:

sitearch='/usr/local/lib/perl/5.6.1'
sitebin='/usr/bin'
sitelib='/usr/local/share/perl/5.6.1'

A little context: the Linkstation is an embedded system, and perl would have
been built on a host system with a cross-compiler.  Those long paths in
/var/tmp/hhl-target... are where the target perl libraries would have been
installed on the host machine to avoid conflict with the host machine's
local installation of perl.  Unfortunately some of this information sticks
around in Config.pm when perl is installed on the target, and that is
confusing mod_perl's configuration process, it seems to me.

It is interesting to note that, in this case, if mod_perl had used sitearch,
sitebin, sitelib, and so on, instead of installsitearch and friends, I would
have had a successful install of mod_perl.  I don't know enough about it to
say what mod_perl should be doing in the general case.  Maybe the
cross-compile of perl wasn't done quite right and that mucked up Config.pm.

I promise I didn't do anything out of the ordinary!  My history just shows:

root@LINKSTATION:/usr/local/mod_perl-1.99_17# history | grep Makefile.PL
  139  perl Makefile.PL MP_APXS=/usr/local/apache/bin/apxs
  157  perl Makefile.PL MP_APXS=/usr/local/apache/bin/apxs
  510  history | grep Makefile.PL
