ruby-fann on Linux?

[pete]

Hi All-

I'm trying to install ruby-fann on Linux, I followed installation
instructions, but get this when trying to install the Gem:

Building native extensions. This could take a while...
ERROR: Error installing ruby-fann:
ERROR: Failed to build gem native extension.

Did I miss something? I installed FANN, then tried to run the Gem
install.

Thank you!
