Perhaps this extract from 'man CPAN' might shed some light on this issue:
"
  Finding packages and VERSION

       This module presumes that all packages on CPAN

       · declare their $VERSION variable in an easy to parse manner. 
         This prerequisite can hardly be relaxed because it consumes far 
         too much memory to load all packages into the running program just
         to determine the $VERSION variable. Currently all programs that are
         dealing with version use something like this

             perl -MExtUtils::MakeMaker -le \
                 ’print MM->parse_version(shift)’ filename

         If you are author of a package and wonder if your $VERSION can be 
         parsed, please try the above method.
"

$ perl -MExtUtils::MakeMaker -le 'print MM->parse_version(shift)' DBSchema/DBD/Pg.pm
Could not eval '
            package ExtUtils::MakeMaker::_version;
            no strict;

            local $DBD::Pg::VERSION;
            $DBD::Pg::VERSION=undef; do {
                  if $DBD::Pg::VERSION != 1.32 && $DBD::Pg::VERSION < 1.41;
            }; $DBD::Pg::VERSION
        ' in DBSchema/DBD/Pg.pm: syntax error at (eval 4) line 7, near "if
$DBD::Pg::VERSION "
undef

( then move the $VERSION setting up a few lines as above )

$ perl -MExtUtils::MakeMaker -le 'print MM->parse_version(shift)' DBSchema/DBD/Pg.pm
0.10

This also happens with the latest ExtUtils::MakeMaker 6.3 , so I guess this
is simply a limitation of all MakeMaker implementations that module writers
have to work within, as mentioned in the CPAN documentation.
