child_process doesn't work with fibers

[lm1]

For the testcase:

require('child_process').exec('echo A', function(err, stdout){
  if (err) console.log('Error:', err);
  else console.log('Output:', stdout);
});

I'm getting the following error with node-fibers loaded:

Error: { message: 'Command failed: /bin/sh: symbol lookup error: /home/lm/node-fibers/coroutine.so: undefined symbol: dlsym\n',
  stack: [Getter/Setter],
  killed: false,
  code: 127,
  signal: null }

Hey what OS & Node version are you running? I can't reproduce this on OS X Snow Leopard with node 0.3.x or Gentoo Linux with node 0.2.x or 0.3.x.

Could you apply this patch to the makefile and then run "make clean all" and tell me if it fixes the problem?

Yes, it resolves the issue -- thanks!

Great! I went ahead and committed that in a203d61.
