Here's another issue happening which I am looking into but just 
reporting in case anyone knows what's going on.  Bash has brace 
expansion which works like
echo {one,two,red,blue}
one two red blue

So if you did mkdir -p stuff/{things,things1,things2} you expand to 
mkdir -p stuff/things stuff/things1 stuff/things2.   This is used 
heavily in rpm spec files and this used to work.  Our shell is working 
properly in that if you enclose the braced item in quotes it will not 
expand them but rather just use it literally

echo '{one,two,red,blue}' will echo that brace string literally.

So in rpm there is a line like mkdir -p 
$RPM_BUILD_ROOT/{bin,usr/bin,usr/man/man1}
But what is actually being executed is
mkdir -p '/var/tmp/pdksh-root/{bin,usr/bin,usr/man/man1}' which doesn't 
expand the braces which causes a failure.  I'm not sure who is to blame 
yet, and more importantly I'm not sure if some packages are working 
while others are not.

Thanks,
Mark
