Trying to build Perl distribution from sources. Installation directory needs to be specified before the build, as a parameter to Configure utility (e.g. /usr/local/myperl). As far as I understand, if I wanted to install that Perl distribution on another host, it must be put into the same directory (/usr/local/myperl). Is there a way to make it location-independent? I would like to be able to unpack it to any directory (specified by the host owner), set up necessary environment variables (PATH, etc.), so that it would work.
Edit: Created Perl 5.30.0 distribution using -Duserelocatableinc option.
Below is perl -V output:

Normally there's numerous hard coded paths in a Perl installation. What you're looking for is "Relocatable @INC".
To create a relocatable perl tree, use the following command line:
sh Configure -DuserelocatableincThen the paths in @INC (and everything else in %Config) can be optionally located via the path of the perl executable.
Also be sure to read README.aix for special AIX instructions.
