Under Perl 5.10, Cache::Mmap yields this warning: Version string '' contains invalid data; ignoring: '' at /usr/local/ lib/perl5/site_perl/5.10.0/darwin-2level/Cache/Mmap.pm line 36. The solution is to use a more modern version comparison. It currently has this: use constant has_utf8 => defined($^V) && $^V ge "\5\6\0"; I've Cc'd John Peacock, master of all things Version. John, can you recommend a more correct and backwards compatible way to do this? Thanks, David

Ick. That was always a bad idea (Perl documentation notwithstanding). This is guaranteed to work everywhere: use constant has_utf8 => $] >= 5.006_000; HTH John
