Perl DBI and DB2 modules installation on AIX 6.1

My AIX6.1 natively didnot have c compiler.So, I have downloaded xlc compiler to compile and install perl DBI and DB2 modules.
Also, DB2 module installation using perl5.8.8  failed with Usage: Cwd::fastcwd()  error.

# Here are the debugging steps I have performed to install DB2 module using perl 5.14.2 #
AIX Tools for linux:
http://www-03.ibm.com/systems/power/software/aix/linux/toolbox/ezinstall.html 

Install xlc_r compiler as follows:
http://www-01.ibm.com/software/awdtools/xlcpp/aix/   - xlcpp  compiler (aix c/c++ compiler)
xlcpp installation guide:https://www-304.ibm.com/support/docview.wss?uid=swg27017988&aid=1

Command to install:
installp -aXYgd ./xlcpp/usr/sys/inst.images -e /tmp/install.log all
export PATH=$PATH:/usr/vac/bin:/usr/vacpp/bin

You need to find a working C compiler.
Either (purchase and) install the C compiler supplied by your OS vendor,
or for a free C compiler try http://gcc.gnu.org/
I cannot continue any further, aborting.

Trouble shooting:
export PATH=$PATH:/usr/vac/bin  (for xlc_r compiler in PATH)
use -Dcc=xlc_r (xlc_r installed manually)

Looking for extensions...
A number of extensions are supplied with perl5.  You may choose to
compile these extensions for dynamic loading (the default), compile
them into the perl5 executable (static loading), or not include
them at all.  Answer "none" to include no extensions.
Note that DynaLoader is always built and need not be mentioned here.

Stripping down cppstdin path name
End of configuration questions.

Stripping down executable paths...
Creating config.sh...
If you'd like to make any changes to the config.sh file before I begin
to configure things, do it as a shell escape now (e.g. !vi config.sh).

make
make test
make install

/usr/opt/perl5_32/lib/5.14.2/aix-thread-multi/Config.pm   file now contains  xlc_r and proper archlib path to perl
5.14.2.
