Somewhere I've mis-configured my path to man3. When using the CPAN shell, my 'make test' points to the proper perl installation: 
Running make test
PERL_DL_NONLAZY=1 /home/desantis/perl64root/perl/bin/perl "-Iblib/lib"
+ "-Iblib/arch" -w test.pl

[download]
But 'make install' tries to put man3 under tdesantis instead of desantis. 
Running make install
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
+!!
ERROR: Can't create '/home/tdesantis/perl64root/perl/man/man3'
mkdir /home/tdesantis: Operation not applicable at /home/desantis/perl
+64root/perl/lib/5.8.8/ExtUtils/Install.pm line 478

I read and followed the excellent advice: http://www.perlmonks.org/?node_id=605420 and added the following to my makepl_arg key in CPAN/Config.pm: 
INSTALLMAN3DIR=/home/desantis/perl64root/perl/man/man3

[download]
as well as this to my .modulebuildrc: 
--installpath libdoc=/home/desantis/perl64root/perl/man/man3

[download]
But still no luck. What am I overlooking?
