Amen to that. After some pretty horrible experiences, I now keep my application Perl (self-compiled) well clear of my system Perl (liable to surprise upgrades). This also means that I can develop with Perl 5.10 when the distribution still thinks that 5.8.8 is the latest and greatest.

<sigh/> I miss my AIX. Wonder if I should look out for an old RS/6000 on eBay. Ah, nostalgia ain't what it used to be.
