[SPTUsers] Installation woes

[Scot Wilcoxon]

> opendir(./../..): Permission denied at ./sptinstall-1.1.0 line 264
line 264 is:
    my($OurHomeDir) = getcwd();

so getcwd() is failing.

I suspect that reading/searching of one of the parent directories is not
allowed.  The permissions on directories have to be "x" so you can
access files inside the directory, and the "r" flag is needed to get a
list of files in the directory.

Maybe /home does not have "r" permission so users can't see what is in
that directory, or /home/webquest might not have that permission so
other users can't see what is in the directory.
