Just tried that here, no such luck: 

$ ln -s libGL.so libGL.so.1
$ LD_LIBRARY_PATH=$PWD:$LD_LIBRARY_PATH apitrace trace --api gl
./vtkRenderingCoreCxxTests "TestTranslucentLUTDepthPeeling"                     
apitrace: loaded into /usr/bin/apitrace                                         
apitrace: unloaded from /usr/bin/apitrace                                       
apitrace: loaded into /ssd/src/VTK/build-tmp/mesa_bug/vtkRenderingCoreCxxTests  
apitrace: tracing to
/build/apitrace/src/apitrace-7.1/build/wrappers/glxtrace.cpp:97195: void (*
_wrapProcAddress(const GLubyte*, __GLXextFuncPtr))(): Assertion `procPtr !=
(__GLXextFuncPtr)&glXCreateContextAttribsARB' failed.

Looks like you did get a trace from it, though, so I wonder what's different.
Thanks for uploading that, hopefully that will make it easier to track down!
