I encountered the same issue and need to dig into it.

Thanks to Joerg Sonnenberger I finally figured out where the problem
was: MesaLib don't export that symbol:
trevor@bert:/data/pkgsrc/graphics/cairo$ readelf --syms
/tmp/pkgsrc/graphics/MesaLib/work/.destdir/usr/pkg/lib/libGL.so|grep
glXGetProcAddress
   951: 000000000002e6e0    25 FUNC    GLOBAL DEFAULT   12
glXGetProcAddressARB
  5567: 000000000002e700     5 FUNC    LOCAL  HIDDEN   12 glXGetProcAddress
  5959: 000000000002e6e0    25 FUNC    GLOBAL DEFAULT   12
glXGetProcAddressARB
trevor@bert:/data/pkgsrc/graphics/cairo$ readelf --syms
/tmp/pkgsrc/graphics/MesaLib/work/.destdir/usr/pkg/lib/libGL.so|grep
glXGetProcAddress
   135: 000000000002e730     5 FUNC    GLOBAL DEFAULT   12 glXGetProcAddress
   952: 000000000002e710    25 FUNC    GLOBAL DEFAULT   12
glXGetProcAddressARB
  5958: 000000000002e710    25 FUNC    GLOBAL DEFAULT   12
glXGetProcAddressARB
  6806: 000000000002e730     5 FUNC    GLOBAL DEFAULT   12 glXGetProcAddress

for the moment I edited work/Mesa-7.4.4/src/mesa/drivers/x11/glxapi.c
and put a "PUBLIC" in front of glXGetProcAddress definition at line 1412
as well as
/tmp/pkgsrc/graphics/MesaLib/work/Mesa-7.4.4/src/glx/x11/glxcmds.c and
remove the alias stuff (I was unsure whether it works or not) around
line 2940.

With that change graphics/cairo compiles fine as well as dependent
libraries.

Thanks Joerg,
Jens
