my thanks to those who wrote me off-list and suggested
that I check my installation process
which was to add the above as -new- packages.

Since the above packages are not new, but upgrades,
I saved the original files, from TeXLive 2004,
copied all the files into the appropriate original folders,
checked to see if copacetic
and discovered no xcolor.sty!

so now I know how to use
latex xcolor.dtx

and texhash

<sigh> reading the documentation: never fails to enlighten one!

I am progressing on my beamer slides and back on schedule.
