   Not to start a OS war/flame, but...

   To some extent, I can understand Apache, as it isn't a Sun supported 
product (at least not a seriously supported product), but not installing 
Perl could cause other problems, even if you symlink /usr/perl5/bin/perl 
to your own distribution, as Solaris programes that use perl expect 
/usr/perl5/bin/perl and and may well expect the Sun distributed 
components.  If you want your users or other apps to use your compiled 
Perl, replace /usr/bin/perl with yours, and leave the Solaris Perl intact.

   As for out-of-date, this isn't as true as it used to be, and the Solaris 
sendmail version is not only up-to-date, but is designed to work with all 
the components in Solaris that deal with smtp.  I understand the need to 
be on the bleeding edge, but if this is desireable _and_ stay with 
Solaris, why not just use OpenSolaris?  The Perl and Sendmail in 
OpenSolaris _are_ the most current stable versions (as are many other 
items, like Apache, Samba, etc.).

   On the other hand, these are your systems you can do as you please (but 
as I am curious as to why you use Solaris, and replace core items, feel 
free to contact me off-list and clue me in as to your reasoning).
