 Yes, but only a modified version that I've not managed to commit
because I didnt have commit privs :)

 'make' works for me (except for the other errors) but this equation
passes okay.

 I've got eurmo10 tex font metric file here on my system:

$ locate eurmo10
/usr/share/texmf-texlive/fonts/tfm/adobe/palatino/eurmo10.tfm

 which I think makes it the font metrics for roman oblique palatino.
Maybe you're missing this...

The typesetting is all wrong because LaTeX sees it 'ln' as 'l' times
'n', and 'tan' as 't' times 'a' times 'n'. The parentheses are
probably unneeded too. And TWI is one word, so mbox it:

\begin{equation}
\mbox{TWI} = \ln\frac{a'}{\tan\beta}
\end{equation}

Much better!
