ctest -V was monumentally helpful...

ld.so.1: executable: fatal: libstdc++.so.2.10.0: open failed: No such 
file or directory

...I bet that's the problem in most/all cases. Ok, turns out (well, I 
sort-of knew this before, but) g++ is broken, at least in that binaries 
it produces all have this problem. Which means I seem to have found a 
"bug"; tests that involve compiling C++ programs either a: ignore that I 
was using CC=cc CXX=CC to build cmake, or b: fail to notice that g++ 
produces broken executables. (I'm attaching the full output of 
'VERBOSE=1 bin/ctest -V -I 63,63'.)

After forcing the issue with 'CC=cc CXX=cxx bin/ctest', the test suite 
passes.

On a different note: I thought the verbose output was always written to 
a file somewhere; is this not the case?

FYI test 47 is leaking output as follows:
  47/ 67 Testing wrapping                      sh: 
QT_MOC_EXECUTABLE-NOTFOUND: not found
sh: QT_UIC_EXECUTABLE-NOTFOUND: not found
    Passed

Another note: running test 63 "broken" once made it almost impossible to 
clean things up and re-run with the right compilers... ultimately I did 
'rm -rf Tests' and re-unpacked the tarball to fix it. Is it supposed to 
be that difficult? (I did try nuking just Tests/SubDir/CMakeFiles first, 
to no effect.)

Anyway, thanks for the quick help!
