Compiling Module questions

Hello -
My company just acquired an HP Itanium server; a perl 5.8.8 depot file
was installed on it and perl-v indicates:
This is perl, v5.8.8 built for IA64.ARCHREV_0-thread-multi-LP64
(with 33 registered patches, see perl -V for more detail)
Copyright 1987-2006, Larry Wall
Binary build 817.1 [268662] provided by ActiveState
http://www.ActiveState.com
Built Sep 19 2006 13:50:51

I need to install a variety of modules to support other applications;
some of these modules require compilation. The UNIX admins installed an
HP compiler bundle on the server; there are two compilers in that
bundle; 'which cc' points to the first one
/opt/aCC/bin/cc:
HP C/aC++ for Integrity Servers B3910B A.06.15 [May 16 2007]
/usr/ccs/bin/cc_bundled:
HP aC++/C for Itanium(R)-based systems B3910B A.05.50 [May 15
2003]

I have always heard that "you should compile modules using the same
compiler that built perl". perl -V shows: cc='cc' ... ccversion='B3910B
A.05.55'. Does that mean the same exact version? More to the point, can
I safely compile modules using one or both of the compilers above? Does
it matter which?

Thanks in advance.
Paula

There are PPM repositories for HP-UX (both PA-RISC and Itanium, 32-bit
and 64-bit each). You may be able to install your module simply with:

ppm install Module

If the module is available on CPAN and compiles/tests cleanly on HP-UX.

aCC is the proper ANSI C/C++ compiler from HP. You need to use this
one.

This is the free C compiler that comes bundled with HP-UX and doesn't
need to be installed separately. Unfortunately it doesn't support ANSI
C, which is required by Perl nowadays. You cannot use this one.

You can use either aCC or GCC to compile module for ActivePerl on HP-UX.
ActivePerl would detect automatically if you don't have aCC on your PATH
and try to use GCC instead, but since you already have aCC, this doesn't
matter to you.

Yes, I saw the HP-UX repositories but they don't contain all the modules
I need; I need DBD::Oracle and DBD::DB2. Rather then have a mish/mash of
install methods by module I thought it best to use the standard CPAN
process.
