install issues

[Ronald G Minnich <rminnich@lanl.gov>]

xen shares a problem with a lot of python installers: if you build the 
xen on a file system mounted with root squash, the install fails:

if [ -r System.map -a -x /sbin/depmod ]; then /sbin/depmod -ae -F 
System.map -b / -r 2.6.16.13-xen; fi
make[3]: Leaving directory

This is a particularly annoying attribute of many python install tools, 
that you can't run it as root and you can't NOT run it as root.

I don't know how this ought to be fixed, but note that (e.g.) linux 
install gets this one right.
