  Here's the tail end of a ./configure run from cairo; I can send  
the entire config.log if desired.  I'll have to re-do the two pango  
builds...that's not a big deal; I'll try to do that tonight.  In the  
meantime let me know if you want the entire cairo config.log or if  
this will suffice.  (there's more to my reply below this block)  This  
is from a G5 running 10.4, the output is identical to that of an x86  
running 10.6 with the exception of "ps testing".  Again, these are  
the builds that don't work.

---------------------------------------
cairo (version 1.8.10 [release]) will be compiled with:

The following surface backends:
  Image:         yes (always builtin)
  Xlib:          yes
  Xlib Xrender:  yes
  Quartz:        yes
  Quartz-image:  no (disabled, use --enable-quartz-image to enable)
  XCB:           no (disabled, use --enable-xcb to enable)
  Win32:         no (requires a Win32 platform)
  OS2:           no (disabled, use --enable-os2 to enable)
  PostScript:    yes
  PDF:           yes
  SVG:           yes
  glitz:         no (disabled, use --enable-glitz to enable)
  BeOS:          no (disabled, use --enable-beos to enable)
  DirectFB:      no (disabled, use --enable-directfb to enable)

The following font backends:
  User:          yes (always builtin)
  FreeType:      yes
  Win32:         no (requires a Win32 platform)
  Quartz:        yes

The following functions:
  PNG functions: yes

And the following internal features:
  gcov support:  no
  test surfaces: no (disabled, use --enable-test-surfaces to enable)
  ps testing:    yes
  pdf testing:   no (requires poppler-glib >= 0.9.2)
  svg testing:   no (requires librsvg-2.0 >= 2.15.0)

  Under OS X, that'd be "otool -l `which gschem`".  Its output is  
much longer and less useful than ldd.  Here's the relevant section:

          cmd LC_LOAD_DYLIB
      cmdsize 56
         name /usr/X11/lib/libcairo.2.dylib (offset 24)
   time stamp 2 Wed Dec 31 19:00:02 1969
      current version 10803.6.0
compatibility version 10803.0.0
Load command 16

  (interesting timestamp...it bears no resemblance to the timestamp  
on the file itself)

  I wish we could find out how it was built.

                  -Dave
