I think you probably wanted to be in /tmp/dest here, but the result is
still the same: mkdir always tries to recreate the original directory.

Greg Freemyer mentioned the -print0 and -0 options to find and xargs,
respectively. (Actually, the only reason I don't get the credit is
because Mozilla crashed on me *&(*(&^&%*&^(&)*(*_)*&*^% as soon as I hit
the "send" button, but I am not complaining... errr, ummm.. )

Greg suggests an innovative approach, but while I was mucking about with
find and xargs, I found another solution, which I think is actually much
simpler. The find command has a -exec option which does exactly what the
xargs pipe does. Try this:

cd /tmp/origin
find . -type d -exec mkdir -p '../dest/{}' \;

"mkdir -p" will create any necessary parents (in this case, /tmp/dest).
The semi-colon does need to be escaped, and the single quotes are
probably necessary, to prevent shell interpretation of the {} (which
stands for "the current file" in find).
