Percentage width doesn't work with recent texlive

[N. Andrew Walsh]

Hi List,

on my system, I have a distro-provided texlive, which just updated. After
that updates, two things have changed in my document:

1) the custom language definitions I had in the preamble to define
'ngerman' and 'american' languages are no longer necessary for LyX, but also
2) the percentage definition for figure wrap widths no longer works. I get
an "invalid unit" error from the compiler.

I can just comment out those custom language definitions, but how do I fix
the percentage-width error I'm getting? Is there some package I need?

Thanks for the help,

A
