There is a symbol conflict between Berkeley DB 1.xx, the ndbm library
and Sybase's DB-Library. This means that you can't use the default
perl version that is installed on linux to build the Sybase::DBlib
part of sybperl.

The solution is to rebuild perl without -ldb and -lndbm. I've done the 
following, although there are of course other ways of doing this:

Get the latest perl source from www.perl.com. You might as well
install the latest stable version of perl if you're going to do this,
aren't you?

Unpack, and then run (in the perl source directory):

	./Configure -ders -Dlibs="-lnsl -lgdbm -ldl -lm -lc -lposix -lcrypt"
	make
	make test

If all is well at this point, su to root, and

	make install

Now go to the sybperl source directory, and do 

	perl -V:libs

to verify that your perl binary is not referencing -ldb or -lndbm any
more. You can also do

	ldd `which perl`

which should give you something like

troll (6:55AM):456 > ldd `which perl`
        libnsl.so.1 => /lib/libnsl.so.1 (0x40007000)
        libgdbm.so.2 => /usr/lib/libgdbm.so.2 (0x4000d000)
        libdl.so.2 => /lib/libdl.so.2 (0x40013000)
        libm.so.6 => /lib/libm.so.6 (0x40017000)
        libc.so.6 => /lib/libc.so.6 (0x40030000)
        libcrypt.so.1 => /lib/libcrypt.so.1 (0x400d5000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x2aaaa000)

Now you are ready to build sybperl. Follow the directions in the
README, and remember to edit CONFIG and set SYBASE and EXTRA_LIBS
correctly.
