GWorkspace on OpenBSD

[Sebastian Reitenbach]

Hi,

I had some trouble to get GWorkspace to run on OpenBSD 4.1. I took the 
OpenBSD ports from http://mail.rochester.edu/~asveikau/gnustep-openbsd/, 
updated them to use gnustep-make-2.0.1, gnustep-base-1.15.0, 
gnustep-gui-0.12.0, gnustep-back-0.12, and GWorkspace-0.8.6. 

After installing, trying to start it, GWorkspace aborted with the following 
message:

Critical Error in GWorkspace
NSInvalidArgumentException: NSTask - launch path (mount) not valid

It took me a while to find out what this message wants me to know. After 
running GWorkspace it in the debugger, I saw it stopping here:

The problem is easily explained: on OpenBSD mount is in /sbin, not 
in /bin. /sbin is not in $PATH environment variable of the user, therefore 
GWorkspace does not find the mount command automagically. The fix is to 
add /sbin to the PATH environment variable. With this done, I see another 
error message on the console regarding mount. Mount is called with 
parameter -p (on Linux to specify a file descriptor to read passwords from). 
This parameter does not exist on OpenBSD, therefore at least one call to 
mount fails, but does not seem to be fatal.

kind regards
Sebastian
