If neither of these addresses is the proper place to direct this inquiry, please let me know (and redirect me if you know where I should go).  

I have installed the package screen-3.9.9 for sparc-solaris7 from sunfreeware.com, and am having a bit of difficulty.  I have searched on altavista and google for help on this, and found the FAQ, but with no real luck.  If you know where I can find this information in a public forum, I am glad to look there.  I am familiar  with system administration, but by no means an expert.

screen has been installed on the machine (by me, from root, using pkgadd) with suid attibutes.  When I try to run it from any user (david, or root) I get the following:

bash-2.05$ screen
You are not the owner of /tmp/uscreens/S-david.
bash-2.05$ whoami
david
bash-2.05$ ls -l `which screen`
lrwxrwxrwx   1 root     other         12 Oct 11 14:38 /usr/local/bin/screen -> screen-3.9.9
bash-2.05$ ls -l `which screen-3.9.9`
-rwsr-xr-x   1 bin      bin       703905 Aug 29 05:18 /usr/local/bin/screen-3.9.9
bash-2.05$ pwd
/tmp/uscreens
bash-2.05$ ls -l
total 32
drwx------   2 bin      staff         69 Oct 22 09:22 S-david
drwx------   2 bin      other         69 Oct 22 00:45 S-root

I have read the included man page and /usr/local/doc/screen/INSTALL, and the FAQ at http://www4.informatik.uni-erlangen.de/~jnweiger/screen-faq.html.  I have tried changing the owner of S-david to david, and screen starts, but then can't get a pty.

Any ideas what is going on and how to fix it?
