on 2012-07-17 :

As part of my initial install, configure displays a Software Error on the page without finishing loading the rest of the settings after CGI setup:
Argument "5.8.1" isn't numeric in numeric lt (<) at /srv/http/twiki/lib/TWiki/Configure/Checker.pm line 307.
RCS is version 5.8.1 and this only happened when I installed it so I know that must be what it is. I'm not sure where to go from here.

It looks like configure is failing to detect RCS properly in some circumstances. Suggested patch:
