Thanks very much for the packaging.

I think I found the answer about missing glyphs.  I followed the debugging
advice that BDR put in that bugzilla entry mentioned in my last note.  The
culprit was a copy of the microsoft symbol.ttf was in my user account font
folder.  That used to be a good thing, but apparently no more.  It causes
1) R to not be able to display lceil and other large braces and 2) Evince
cannot display some sizes of "mu" and "<=".  As soon as that file is
removed, then everything seems to display just fine.

Oh, one more thing. I can confirm the claim in that bug report that R
itself is writing proper PDF output, the problem is only in the display on
screen in a given system.  Embedding the fonts always solves this trouble,
however, so if one is unable to remove a troubled font or fiddle around it,
there is still a straightforward fix.
