[lucida] Lucida and Nath

Hi guys,

I bought the fonts from Y&Y back in 2002 and have been a happy user ever
since. Today I updated by Debian unstable system and got a new version
of TeX Live, version 2009, I believe. I then discovered that the
texlive-fonts-recommended package no longer carries lucidabr.sty :-(

After downloading the package from


and installing it, I could again compile my document.

However, I now get an error about "Leaders not followed by proper glue."
when I compile the following minimal document with the Nath package:


  $x \mapsto y$

The output is:

  % pdflatex \\nonstopmode\\input test.tex
  This is pdfTeX, Version 3.1415926-1.40.10 (TeX Live 2009/Debian)

Can others reproduce this? The Nath package has this to say about
the \mapsto macro:

Can anybody explain how I should change it to be compatible with the
updated lucidabr.sty file?
