I like to install a perl that is in a completely different
directory than the system perl. I have a script that
unpacks the perl distribution, runs configure, and installs
the modules such as DBD. I have to be very careful when
the script installs the modules that the step
perl Makefile.PL
runs the correct perl, so I just give it the full path:
/home/username/perl5/bin/perl Makefile.PL
Also, I am careful to use separate directory trees for the
perl build and the perl installation. So I compile
perl in
/home/username/perl5_build.
I compile the modules in
/home/username/perl5_build/modules.
I developed this methodology to make my perl builds
reproducible and not depend on ppm working properly.
I like ppm but I have seen it get confused and trash
things too many times. Building everything from source
is tedious but I have found it to be worthwhile and
rewarding.
Other advantages of this approach are :
- I can install a new version of perl in a new
directory and try it without losing my old version.
- When I change to using a different computer my
perl environment moves with my home directory.
- My script documents my build so that someone
else can reproduce my system.
It should work perfectly the first time! - toma
