2032160 - Migrated from ASE 12.5 to ASE 15.7 and one appliation is getting a fatal error, permission denied - but permissions are set correctly - SAP ASE

Upgraded from ASE 12.5 to ASE 15.7 and one of the applications on Unix is getting the below error:

ld.so.1: run_sql: fatal: /appl/sybase/OCS-15_0/lib/libct_r.so: Permission denied

However, the directory lib directory above and permissions look correct.  Any idea what we are missing in terms of permissions?

/appl/sybase/OCS-15_0/lib: ls -lrt libct_r*

lrwxrwxrwx   1 sybase   sybase        13 Jun  3 15:18 libct_r.so -> libsybct_r.so*
