My apologies for the triplicate posts.
For whatever reason the submit page would not update last night.
Apparently I unknowingly submitted the post three times!
Okay, my goof --- I plumb forgot about the Package Browser site. Bookmarked!
I had removed the lesstif package from my system. Never used the package and I removed. Why tightvnc needs lesstif is beyond me.
I reinstalled the lesstif package. However, the tightvnc build script still refused to compile unless I temporarily granted exec permissions to /tmp. I prefer to run my build scripts in a sandbox build area that uses a different tmp directory.
The tightvnc package seems to have built okay.
I wonder whether I have to keep lesstif installed.
Also, while it is fine and dandy to have a LQ thread about problems with SlackBuilds.org scripts, you really should post these questions to the maintainer of the script (listed in the .info file) and to the SBo mailing list.
You're probably correct. Bad hair day yesterday I guess. So I think I'll go to my room and think about things for a while!
Thanks for the help everybody.
