I also tried compiling this version libunwind-1.1.tar.gz and got similar response.
===========================================
4 of 33 tests failed
===========================================
make[2]: *** [check-TESTS] Error 1
make[2]: Leaving directory `/home/temporal/libunwind-1.1/tests'
make[1]: *** [check-am] Error 2
make[1]: Leaving directory `/home/temporal/libunwind-1.1/tests'
make: *** [check-recursive] Error 1
Complete make check log can be also found attached to this message.
Thank you for your help,
