dev_appserver.py can't start _go_app - OSError: [Errno 13] Permission denied

[Saratogan]

Hi,

I succeeded in following/coding/testing and uploading the Hello World! Go app engine tutorial using native Windows 8 tools (after I sorted out windows Python + cygwin issues).  But I want to continue dev on Linux.  But I am having problems getting dev_appserver.py to start the tutorial's _go_app (built successfully).  Configuration and debug log below.  I checked and verified  permission on every file and dir I could find in the log.  What could be the problem? 

Thank you in advance for your help.

Sincerely,
Saratogan

go version go1.1.2 linux/amd64

Go App Eng SDK 1.8.5 (probably not necessary but I "chmod -R r+x go_appengine/")

Just a random guess, is /tmp mounted noexec?

You nailed it!

Thank you very much.
