Try to compile, but stuck at the following:
....
checking for flex version... invalid
configure: error: Found invalid flex version: 2.5.33. Supported flex
versions are: 2.5.4.
Is there any way to specify the alternate path for the flex as I don't
want to mess with existing system? The 2.5.33 is reside in /usr/bin/
flex, and 2.5.4 is installed in /usr/local/flex.2.5.4/
