Have you installed the 32-bit libraries? From the top of my head I can't tell what the respective package is called, but it shouldn't be too hard to find out — the package includes ld-linux.so, libc.so, and many of the other common libs in 32-bit versions.  In general, it shouldn't be a problem to run 32-bit programs on a x86_64 system... (I'm doing it all the time)

Update: the respective package is "glibc-32bit" (glibc-32bit-2.6.1-18.x86_64.rpm for SuSE-10.3).

It contains all the libraries needed by a SuSE-built 32-bit perl binary, i.e.

/lib/ld-linux.so.2
/lib/libc.so.6
/lib/libcrypt.so.1
/lib/libdl.so.2
/lib/libm.so.6
/lib/libnsl.so.1
/lib/libpthread.so.0
/lib/libutil.so.1
