This is a bug report for perl from rurban@cpanel.net,
generated with the help of perlbug 1.39 running under perl 5.15.8.


-----------------------------------------------------------------
win32 lacks usability with a default install, and the 
workarounds are poorly documented.

1. SITELIB is not in the @INC path with a default install, as 
perl.c overrides the config.h definitions with a custom and 
undocumented registry search. This registry entry is fine for 
vendor packagers, but is not created by the default installation.

Either keep the sitelib/sitearch and vendorlib/vendorarch default 
entries in config.h and allow overrides from the registry (similar to PERL5LIB).

Or create the necessary registry entry in installperl. 
Better not. Registry entries should be optional.

The problem is that one cannot install further modules without proper sitelib/arch 
entries in @INC via cpan.

README.win32 says:
Perl does not depend on the registry, but it can look up certain default 
values if you choose to put them there.

This is wrong. Without a registry for sitelib entry cpan installations 
will silently fail. "Cannot find ..." even if they are installed correctly.


2. CPAN creates unusable default entries in .cpan\CPAN\MyConfig.pm
See [CPAN #76831]. nmake is added with the full path, which usually 
contains spaces, which are not quoted. The nmake test system call 
passes interestingly, nmake install fails with cpan.
