Error installing DBD::Sybase

Hi
I tried installing DBD Sybase but encountered many errors along the
installation process. Please let me know if anyone has seen the errors
below. Am I missing some other dependency module?

Attempting to install DBD Sybase from cpan sheel fails. Manual install
also fails. (I use perl 5.8.5.)
1. In the CPAN shell, type in install DBD::Sybase.
Module DBD::Sybase should install without errors and without me having
to tinker with CONFIG, environment variables, #ifdef in .c files. That
is not the case though

Part of Error Log:
==============================================
CPAN.pm: Going to build M/ME/MEWP/DBD-Sybase-1.08.tar.gz

Please set SYBASE in CONFIG, or set the $SYBASE environment variable
at Makefile.PL line 103, line 44.

If I do add $SYBASE as say /usr/local/sybase, the next error that is
seen is this:

If I add a #if defined block around this variable in dbdimp.c file,
the install process moves on till it encounters this error.

==============================================
The above error happens during make test. So I thought I could go on
without it to install. But install fails with an error that it cannot
link libperl.a

Has anyone faced these errors and how have you solved them?

Thanks.
