Build Notes for the perl-DBD-Pg on AIX 6.1 Need cc_r compiler installed on AIX build system and in /bin. Download DBD-Pg-2.17.1.tar.gz from CPAN. Unwrap the tar file. (gunzip & tar -xvf ) in some directory Go to the subdirectory containing the Makefile of the unwrapped tar file, and run "/usr/opt/perl5/bin/cpan2rpm --author xcat --version 2 ." This will eventually fail but it does produce a spec file in /opt/freeware/src/packages/SPECS. Modify the spec file as needed. Change the name. See DBD-Pg.spec. Put the DBD-Pg-2.17.1.tar.gz file in /opt/freeware/src/packages/SOURCES. Go to /opt/freeware/src/packages/SPECS and run "rpm -bb DBD-Pg.spec", which creates: /opt/freeware/src/packages/RPMS/ppc/perl-DBD-Pg-2.17.1-1.aix6.1.ppc.rpm
