ASE 12.5 for LINUX RedHat 64 bit - download place

[max]

Hi all,

I'm migrating our DWH server from SUN SOLARIS9 to LINUX REDHAT on
intel processor.
Using SAS 9.2 Linux access module to connet from SAS to SYBASE, it
gives me an error about:

ERROR: Could not load /home/sasinst/sas_sw/SASFoundation/9.2/sasexe/
sassyb
(38 images loaded)
ERROR: libct_r64.so: cannot open shared object file: No such file or
directory

I found over the net some threads about it, all talking about
switching from 32 to 64 bit the sybase-common-12.5.0.1DE-1.i386.rpm
and the sybase-openclient-12.5.0.1ESD-1.i386.rpm

I found these packeges on: http://www.sybase.com/detail?id=1020072 but
I can't find the 64bit version of this files, if exists. Where can I
download them?

Thanks in advance,

Massimo
