When I run picl (on OS X), I get this message:

(1228) An error, warning or message was generated, but no description is available
HI-TECH PICC-Lite COMPILER (Microchip PICmicro) V9.60
Copyright (C) 1984-2007 HI-TECH SOFTWARE
(141) An error, warning or message was generated, but no description is available

I've looked up the error codes and the most pertinent is
1228: unable to locate installation directory

I set the environment variable HTC_PICL to the appropriate installation directory (/Applications/HI-TECH/picc/lite/9.60) but that doesn't help. Could it be a permissions problem?

Thanks!
