SID-01503: RCS causes software error on configure

Status:	Answered	TWiki version:	5.1.1	Perl version:	5.16.0
Category:	CategoryInstallation	Server OS:	Arch Linux, kernel 3.4.4	Last update:	5 years ago

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.

Hello,

After I change this code to

m        if ( $version !~ /Can't exec/ && $version =~ /(\d+(\.\d+))/ ) {
