Package ifpdf Error: Name clash, \ifpdf is already defined.

Hi all,

One of my books, that used to compile, now gives me the following error
message:

Package ifpdf Error: Name clash, \ifpdf is already defined.

I can toggle the symptom on and off by including or excluding the following:


\usepackage[bookmarks,
plainpages=false,pdfpagelabels,colorlinks=true,bookmarksnumbered=true]
{hyperref}


Trouble is, without that line, I can't get clickable chapters in the table of
contents. Also, another one of my books has that line and doesn't exhibit
this symptom.

I've tried exploiting the differences, but with two >100 page books, each with
sizeable layout files, I'm hoping one of you has seen this before so I don't
need to keep carving things in half til I can toggle the problem with
something other than the hyperref package.

Thanks

More info. I got the problem down to a single hello world lyx file and a 7
line layout file. I can now toggle the problem by changing the layout's base
document class between memoir and book. The original was written with memoir
and fails. Changing it to book allows it to compile.

Soooo, I need to find a hyperref substitute that works within memoir. As I
remember, memoir is pretty sophisticated, so it probably has its own hyperref
substitute.

Anyone have any ideas?

Thanks
