This still isn't working. Here is what I did: 0) The libraries for 15.0 changed names:

c:\DBD-Sybase-1.08>ls %SYBASE%\OCS-15_0\lib
libsybblk.lib  libsybcs.lib  libsybct.lib  libsybdb.lib

c:\DBD-Sybase-1.08>ls %SYBASE%\OCS-15_0\lib3p
defaultmem.dll  libplc21.dll   nsldapssl32v40.dll
libnspr21.dll   libplds21.dll  sbgse2.dll

c:\DBD-Sybase-1.08>ls %SYBASE%\OCS-15_0\dll
debug           libsybdb.dll     libsybintl.dll   libsybtcl.dll
libsybblk.dll   libsybddce.dll   libsybsdce.dll   libsybunic.dll
libsybcomn.dll  libsybdldap.dll  libsybskrb.dll   nondebug
libsybcs.dll    libsybdreg.dll   libsybsmssp.dll
libsybct.dll    libsybfssl.dll   libsybsrv.dll

1) Modified Makefile.PL to remove the references to the libraries that do not exist:

    if($^O eq 'MSWin32') {
#    $lib_string = "-L$SYBASE/lib -llibct.lib -llibcs.lib -llibtcl.lib
+ -llibcomn.lib -llibintl.lib -llibblk.lib $attr{EXTRA_LIBS} -lm";

    $lib_string = "-L$SYBASE/lib -llibsybct.lib -llibsybcs.lib $attr{E
+XTRA_LIBS}";

Note that some of the previous libraries are now dll's. 2) Run perl Makefile.PL

3) Now run nmake: This is just the last bit....

I have been through the archives at http://www.peppler.org/cgi-bin/searcharc.cgi. I do not find any reference to anyone compiling this for Sybase 15 on Windows. The ppd module located at http://www.peppler.org/downloads/ActiveState/ still is looking for the libraries pre-Sybase 15.0. I did comment out the set line in dbimp.c. So, I'm guessing I'm not changing the library line correctly? Is there something else I need to do? Thank you
