LyX says Tex Gyra Schola is not installed, but I installed it

[Steve Litt]

Hi all,

The only font readable enough for my books is Century Schoolbook. All
the rest are too faint. Most Century Schoolbook implementations don't
work with LyX, or at least I haven't been able to get them to work.
With one exception...

Tex Gyra Schola is a Century Schoolbook implementation that has been
working for me for the past 5 years. But now, When I 
Document->Settings->Fonts and select a Serif font, Tex Gyre Schola is
listed, but the words "(not installed)" are appended, and in fact when
I compile the document, the font in the PDF is definitely not TeX Gyre
Schola.

I installed the tex-gyre and tex-gyra-math packages with the following
command:

tlmgr install tex-gyre
tlmgr install tex-gyre-math

After those commands, I performed a texhash command. I then terminated
LyX and did a reconfigure. Still "(not installed)". 

The other relevant settings on Document->Settings->Fonts are "Use
Non-TeX Fonts" is unchecked, LaTeX font encoding is Default.

What can I do to start to figure out this problem?

Thanks,

SteveT
