DBD Sybase 1.08: Invalid lvalue in Sybase.xsi during MAKE

I'm trying to setup my Perl and DBI/DBD:Sybase development  
environment for the first time on Mac OS X (Tiger v10.4).

I get errors running MAKE after the make Makefile.PL in DBD-Sybase-1.08

I installed XCode to get the C compilers, Make, etc.

I installed Perl 5.8.6

I Installed Sybase OpenClient 12.5.1 ASE Edition and added the  
appropriate environment variables for Sybase. I can connect to my  
database using jSQL.

I downloaded the DBI 1.602 module and did the make Makefile.PL ,  
MAKE, make test, and make install (all went well)

I downloaded DBD-Sybase-1.08 and did the make Makefile.PL , but when  
I try to run MAKE with the MAKEFILE that was generated, I get this  
error:

cc -c  -I/Applications/Sybase/System/OCS-12_5/include -I/Library/Perl/ 
5.8.6/darwin-thread-multi-2level/auto/DBI -g -pipe -fno-common -

in assignmentSybase.xsi: In function

assignmentmake: *** [Sybase.o] Error 1

Does anyone know what I'm missing?

I tried adding "-framework CoreFoundation" to the EXTRALIBS and  
LDLOADLIBS lines in the MAKEFILE that was generated, but it had no  
effect.
