Hi Scott,
I think that may be some library file got overwritten by other programs. I tried to reinstall amber16, but it didn't solve the problem.
I copied the compiled antechamber executable in "../to_be_dispatched/antechamber" to another workstation which doesn't have amber installed. It can print out welcome message.
$./antechamber
Welcome to antechamber 17.3: molecular input file processor.
./antechamber: Fatal Error!
AMBERHOME is not set.
Best,
Yuan

Hi,
Why do you think anaconda3 is the problem ?
PLease enter this command:
/usr/local/software/amber16/bin/to_be_dispatched/antechamber
If it seg faults then it is clear that the problem is antechamber (or some antechamber specific OS preamble).
I do not have problems with:
gcc version 4.8.5 (GCC)
Red Hat Enterprise Linux Server release 6.9 (Santiago)
