CPAN installs the packages into /usr/local hierarchy and it doesn't have own 
big registry of all installed (dpkg and cpan) packages because it autodetects 
the packages trying to load them.

If I would like to install i.e. Foo::Bar which requires Baz::Bar, the second 
package is just searched in default path 
(/etc:perl:/usr/local/lib/perl:/usr/share/perl:/usr/lib/perl:...). The 
version numbers are placed in module's file so the registry contained 
metainformation is not necessary. 

Perhaps the PEAR could be modified so .registry directory might be searched in 
directories from include_path. I don't know if it would work because the 
*.reg files contains hardcoded paths. See console_getopt.reg:


Even you move i.e. documents from /usr/share/php/docs 
to /usr/share/doc/$PACKAGE/, the PEAR package manager still have old values. 
After `pear upgrade' you will have old files in /usr/share/doc and new files 
in /usr/share/php/docs. Again, the md5sums for Debian packages and 
metainformations in /var/lib/dpkg won't match with PEAR metainformations 
from /usr/share/php/.registry.

I see only one clean solution. Just set the PEAR default directory to 
the /usr/local/share/php. The worst scenario is that PEAR installs the second 
copy of needed package into /usr/local/share/php (i.e. Console_Getopt) but it 
is FAR better than overwriting the dpkg's files in /usr/share/php.
