The first symptom of the problem was that after upgrading Acrobat Reader (acroread), all text in the user interface (menu bar, menus, dialogs) displays as little boxes, not as letters. The debug output from acroread says,

Code:

(acroread:9368): Pango-WARNING **: No builtin or dynamically
loaded modules were found. Pango will not work correctly.
This probably means there was an error in the creation of:
  '/etc/pango/pango.modules'
You should create this file by running pango-querymodules.

(acroread:9368): Pango-WARNING **: pango_shape called with bad font, expect ugly output

(acroread:9368): Pango-WARNING **: pango_font_get_glyph_extents called with bad font, expect ugly output

(acroread:9368): Pango-WARNING **: _pango_cairo_font_install called with bad font, expect ugly output

(acroread:9368): Pango-WARNING **: pango_font_get_metrics called with bad font, expect ugly output


So this is a pango problem, ok.

The file /etc/pango/pango.modules is present, and looks ok. The modules actually exist at the paths indicated. Tried regenerating this with:

Code:
pango-querymodules  > /etc/pango/pango.modules


No effect. Ok, digging some more... acroread should be looking for the 32bit pango modules, and the paths in that file point to the /usr/lib64/pango/1.6.0/modules/, wtf? This is probably why pango says it couldn't find any modules? (This on an amd64 gentoo install)

Hmm, hey wait, there is a /etc/pango/i686-pc-linux-gnu/pango.modules, what is that for? And it's empty, except for saying "ModulesPath = /emul/linux/x86/usr/lib/pango/1.5.0/modules" ? And that dir doesn't exist?

Finally, after much digging... THE SOLUTION: the 32bit pango is in app-emulation/emul-linux-x86-gtklibs. Make sure you have that installed, and then run:

Code:

pango-querymodules32  > /etc/pango/i686-pc-linux-gnu/pango.modules


Everything works, hooray.


P.S. Installed versions:

app-emulation/emul-linux-x86-gtklibs-10.0-r1
x11-libs/pango-1.18.3
app-text/acroread-8.1.2-r2

This was very helpful for me also - thank you very much.

Funny though that I got this error on only one of two amd64 Gentoo machines I installed recently.

Thanks dude, this worked.

I wonder if /etc/pango/pango.modules is used at all on multilib system?
