in thread Regex problem building perl on IBM AIX

Thank you for the reply. I checked latest Cwd (3.33) at and it also has same expression. I anyway over wrote my version with the one from the site and still the same problem.
I downloaded version 5.14.1 and tried to build it on same system, but same error at same location.
Appreciate any suggestions/comments.

      Thanks for the reply. I am trying to build perl 5.14.1 from source on an AIX system. I used Configure with mostly default options but selected yes for multi-thread support. The configure goes fine. However, when I run make, after some time it gives this error (complete info given below). I think it's the miniperl which is having problem with the given regular expression.

        Apparently miniperl doesn't support (?<=pattern)

        You can change the regex to 

         =~ m#\^/#

        You should report this bug upstream
