you may have to run it on a few different files but if you have paxctl installed it will be paxctl -pemrxs /path/to/file. If that works you can remove them with paxctl -PEMRSX /path/to/file and run it again then look at the logs to see what is actually stopping it and just disable the one feature with paxctl to make sure its working properly.
here is the help from paxctl so when you see something specific in the logs you can map it back to a specific feature of PAX.
usage: paxctl <options> <files>
-p: disable PAGEEXEC -P: enable PAGEEXEC
-e: disable EMUTRMAP -E: enable EMUTRMAP
-m: disable MPROTECT -M: enable MPROTECT
-r: disable RANDMMAP -R: enable RANDMMAP
-x: disable RANDEXEC -X: enable RANDEXEC
-s: disable SEGMEXEC -S: enable SEGMEXEC
-v: view flags -z: restore default flags
-q: suppress error messages -Q: report flags in short format
-c: convert PT_GNU_STACK into PT_PAX_FLAGS (see manpage!)
-C: create PT_PAX_FLAGS (see manpage!)
