Re: libperl.so

i removed the perl rpm and installed perl 5.6.0 from source on a redhat
6.2 machine without problems.

i went through a lot of extra steps to ensure cleanliness, however, which
you may or may not be able to do. here's basically what i did:

rpm -e mod_perl
rpm -qa | grep piranha | xargs rpm -e
rpm -qa | grep php | xargs rpm -e
rpm -qa | grep apache | xargs rpm -e
rpm -qa | grep postgresql | xargs rpm -e
rpm -qa | grep ImageMagick | xargs rpm -e
rpm -e perl --nodeps
rm -rf /usr/lib/perl5/5*
rm -rf /usr/lib/perl5/man
rm -rf /usr/lib/perl5/site*
rm -rf ~/.cpan
cd /usr/local/src
mkdir -p packages
cd packages
wget -c ftp://ftp.perl.org/pub/CPAN/src/perl-5.6.0.tar.gz
wget -c ftp://ftp.perl.org/pub/CPAN/src/perl-5.6.0.tar.gz
cd ..
rm -rf perl-5.6.0
tar zxvf packages/perl-5.6.0.tar.gz
chown -R root.root perl-5.6.0
cd perl-5.6.0
rm -f config.sh Policy.sh
sh Configure -Dcc=gcc -Dprefix=/usr -Dman3dir=/usr/lib/perl5/man/man3 -de
make
make test
make install-strip
cd ..
sync

the rpm spec does a lot of extra stuff when building perl. most of it is
to work around perl's installation scheme in order to allow for buildroot
and relocatable mechanisms in the rpm. i decided not to deal with that
anymore.

the method above won't build a perl shared library for you, only a static
one. remove the "-de" from that configure line and it will prompt you on
all of its questions, one of which is to build a shared library. i'm sure
there's a -D flag you can pass it for that too, but i don't know what it
is offhand. consult the perl install docs.

all the rpm -e commands at the top are because those packages either have
things in a "5.005" directory in /usr/lib/perl5, or are packages that
depend on a package with files in such a directory. that's not going to
fly from a base perl 5.6.0 installation, since it will now use a "5.6.0"
directory. i don't understand why perl does that, but that's beside the
point. you can probably get away with just removing the "postgresql-perl"
package instead of the whole postgresql distribution, but yeah, uh
whatever. you'll figure it out.

after installing perl i imagine you could rpm --rebuild those packages
from their .src.rpm files and then install them and they would use the
correct perl paths, or if not i'm sure a couple well-placed symbolic links
would help you. i don't really use any of those packages so it doesn't
matter to me. stuff like apache i typically prefer to install from source
over using an rpm anyway.

anyway, to each his own, i just wanted to chime in and say it's doable.

good luck.
