Segfault in Mac

[Gustavo Sudre]

Hello,

I'm trying to run v2.5.2 in a Mac (10.11.5)  but I get this error:

IDL Version 8.4, Mac OS X (darwin x86_64 m64). (c) 2014, Exelis Visual Information Solutions, Inc.

Warning: Fatal Error: 

_XmGetDefaultDisplay cannot be used prior to VendorS.Initialize, returns NULL

Segmentation fault: 11

Could you help?

Thanks

Gustavo
