Thanks Michael,
When i run "perl -MConfig -wle 'print $Config{installsitelib}'" in the
machine having 5.8.6 and 5.6.1, I get the same result. See below.

However the config.pm has the below entries in 5.8.6 wherein you can see
the difference compared to 5.6.1
[5.8.6]
installbin='/usr/local/perl-5.8.6/bin'
installhtml1dir=''

installvendorbin='/prod/tools/packages/lib/perl5/bin'
installvendorlib='/prod/tools/packages/lib/perl5/5.6.1'
Does the above differences, Tells something. Specifically, in 5.8.6,
installsitelib is having a different root compared its installbin etc..
Please advice.

MakeMaker's PREFIX option bases its installation directories on your
system
Config.pm. INSTALLSITELIB is based on $Config{installsitelib}. The
value
of this is specific to each installation of perl and is determined by
who
compiled and installed perl. Here's some examples from my machine.
$ perl -MConfig -wle 'print $Config{installsitelib}'
/sw/lib/perl5/site_perl/5.8.6
$ perl5.8.1 -MConfig -wle 'print $Config{installsitelib}'
/Library/Perl/5.8.1
$ activeperl5.6.1 -MConfig -wle 'print $Config{installsitelib}'
/usr/local/perl/ActivePerl-638/lib/site_perl/5.6.1
Presumably $Config{installsitelib} for your 5.6.1 is
/usr/local/lib/perl5/site_perl/5.6.1 and for your 5.8.6 is
/usr/local/lib/perl5/site_perl/. If this is so, MakeMaker is acting
as expected. If not then you've found a bug in MakeMaker. Please check
and let us know.

There is one other way. There's a new option, INSTALL_BASE, just added
but
not yet documented. This mirrors Module::Build's --install_base
providing
you with a fixed installation location not based on %Config meaning the
location your modules get installed into doesn't jump around from perl
to
perl.
Its not yet official because of some outstanding coordination problems
with
Module::Build (we're waiting for 0.28 which fixes this) but its not
planned
to change.
You can read more about why PREFIX will never work and about
INSTALL_BASE

Ahh email, my old friend. Do you know that revenge is a dish that is
