Using Perl to connect to Sybase db without Sybase Client in Windows

I an trying to connect to Sybase with Perl. i was trying to use DBD::Sybase to do that but when trying to install DBD::Sybase using perl Makefile.PL, I get the following error:

Please set SYBASE in CONFIG, or set the $SYBAS开发者_如何学运维E environment variable at Makefile.PL line 120, line 44.

I believe I am getting this because i don't have Sybase client installed on my machine. Is there any way around this? I cannot download Sybase client due to enterprise restrictions. If anyone could point me to a source that distributes Sybase in compressed format, then maybe I could download that(I don't have permission to download .exe files).

Look at greeted.org It seems that you can use sybperl with it.
