problem occurs while running specs/two_logs.rb.

error message: symbol lookup error: lib/aio_logger.so: undefined symbol: aio_write64

the spec actually works for a few times, then gives me this error.

the outcome should be .FP (pass, fail, pending), sometimes the pending shows up, other times it crashes.

below is a transcript of the session showing it working then crashing:


## i only touched one spec file
franco@canary ~/workspace/alogr
 % svn st
?      log
?      ext/aio_logger/aio_logger.so
?      ext/aio_logger/mkmf.log
?      ext/aio_logger/Makefile
?      lib/aio_logger.so
M      specs/two_logs.rb

## it crashes on the thrid requirement

 % RUBYLIB=lib spec specs/two_logs.rb
zsh: correct 'spec' to 'psed' [nyae]?

## so i clean and rebuild

## for no reason it crashes on 3rd requirement like before the clean ?!?!?!
