You are aware that centOS 6.3 ( like red hat RHEL6.3) in VERY VERY conservative
It dose not use very new versions of programs.
it's main goal is to be "rock hard" stable.
libXpm.so.4: cannot open shared object file: No such file or directory
that is not the FULL error
it should look something like
or if 64 bit
if you are running a 64 bit os and the maya2013 is 32 bit
you will NEED to install the 32bit version of "libXpm.so.4"
yum search libXpm
--- from the list ---
yum install ????????
replace the ????? with the 32 bit version , both the 64 and 32 bit ARE listed.
it should be "libXpm-3.5.8-2.el6.i686" ( base repo )
and libssl on centos 6.3 ( well me SL6.3 ) is libssl.so.1.0.0
with current security and bug fixes backported to 1.0.0
you can not replace the default libssl.so.1 in cent with libssl.so.6
that will break the system
you can place it someplace that the operating system can NOT SEE IT
then write a launch script for maya that also points to the libssl.so.6
( say put it in the maya folder along with the executable binary program )
