From SnOwy - Ed's Wiki Notebook
Addendum
- Installed also on Pewter -- same error, excused OK.
- irb did not build or install correctly-- ruby already existed as installed by the OS framework :(
- moving ruby symbolic link in (usr/bin) to _ruby (came with the OS :(
- creating new symbolic link to the correct ruby (usr/local/bin)

Conclusion
- DO NOT USE: io/nonblock -then- r, w = IO.pipe -then- n.nonblock = false until we understand the problem better
- conjecture: this *might* be normal behaviour-- look, the pipe gets filled with 105 'a', then 2(4096) more characters what if the pipe is not bigger than 105 bytes?
- is the test just flawed?
Installation
- built from source ruby-1.9.1-p378.tar.gz
- ./configure
- make
- make test -- see below for the sole failed test (that was later commented out)
- sudo make install

Failed unit test after compiling
- for make test
- Commented out this test /Users/eddiema/Documents/ThePlace/ruby-1.9.1-p378/bootstraptest/test_io.rb
- line 11 onward -- tried changing the amount of time to wait from 10 seconds to 60 seconds-- still failed!
- note if I ever have a hang during unblocked writing to a pipe, this will be the culprit.
- Google search did not help finding a solution to this problem (only acknowledged that a problem exists)
