+I'm trying to install from scratch on a CentOS 4.6 system. I installed perl 5.8.8 from source and then added all the required modules via CPAN. When I build ikiwiki from the tarball, I get this message:
+
+ rendering todo/calendar_--_archive_browsing_via_a_calendar_frontend.mdwn
+ *** glibc detected *** double free or corruption (!prev): 0x0922e478 ***
+ make: *** [extra_build] Aborted
+
+I'm kind of at a loss how to track this down or work around it. Any suggestions? --Monty
