PL/Perl on Postgres Plus Advanced Server 9.3
The version of Perl supported for Postgres Plus Advanced Server 9.3 is 5.14. "Enterprise Linux 6.5" distros come with Perl 5.10. Most users choose a precompiled Perl distribution from ActiveState. However, ActiveState changed their licensing model, and ActivePerl 5.14 is no longer available for a free download.The steps below will get you up and running with pl/perl on PPAS 9.3 for RHEL6, OEL6, and CentOS 6.
Step 1: Download Perl from the Perl Archive Network
[root@localhost tmp]# wget search.cpan.org/CPAN/authors/id/J/JE/JESSE/perl-5.14.0.tar.gz
Step 2: Decompress
[root@localhost tmp]# gzip -d perl-5.14.0.tar.gz
Step 3: Extract
[root@localhost tmp]# tar -xvf perl-5.14.0.tar
Step 4: Change current directory
[root@localhost tmp]# cd perl-5.14.0
Step 5: Run the installation shell script
Two non default options are needed, be sure to answer 'y' for 'Building a threading Perl', and 'y' to 'build a shared libperl.so'. This example changes the installation directory to /opt/perl514
Change the default installation directory (optional)
Installation prefix to use? (~name ok) [/usr/local] /opt/perl514
Answer 'y'
If this doesn't make any sense to you, just accept the default 'n'. Build a threading Perl? [n] y
Answer 'y'
Build a shared libperl.so (y/n) [n] y
Step 6: Compile
[root@localhost perl-5.14.0]# make install
Step 7: Source
-bash-4.1$ export LD_LIBRARY_PATH=/opt/perl514/lib/5.14.0/x86_64-linux-thread-multi/CORE:$LD_LIBRARY_PATH
Step 8: Restart the PPAS Cluster
-bash-4.1$ pg_ctl restart -mf -D /opt/PostgresPlus/9.3AS/data/
Step 9: Create language in the desired database
Step 10: Test Pl/Perl using the example from EDB's plperl readme
