I had the problem that Photoshop would hang during an install. Coping the cxoffice, .cxoffice and .loki directories from a working system resulted in the message from cxmaptest that low 16Mb area is not free (got 0x4001c000). I was running with exec-shield supposedly disabled. The solution I found was to disable the cron job that runs prelink and run prelink with -au. Now Photoshop runs cleanly and all I have to do is find out how to keep the first 16M out of prelinks hands.
