All, The issue got resolved after I used the following options and rebuilt Perl.
In the folder where perl .gz file was uncompressed: - make distclean - CFLAGS='-m64 -mtune=nocona' - ./Configure -Dusethreads -Dprefix=/install/perl/v5.18 -des -A ccflags=-fPIC Verified using: /install/perl/v5.18/bin/perl -V:useithreads -V:usemultiplicity Result should be like: useithreads='define'; usemultiplicity='define'; I also upgraded mod_perl to 2.0.8 to get over another error message that is discussed here: http://comments.gmane.org/gmane.os.netbsd.devel.pkgsrc.user/18165 (I've corrected the perl location in my previous mail that was due to a typo). It works fine now, thanks. Rommel.

[ error] Failed requirements: [ error] - Perl built with ithreads (build perl with -Dusethreads) As recommended in the last line - "build perl with -Dusethreads" I tried that while setting up perl but the same error. Please share your inputs to resolve this. Thanks, Rommel.
