I'm currently trying to install the latest version of Ferret (0.10.9)
on my Ubuntu Dapper (6.06) system. I have tried the gem, but it does
not generate the ferret_ext.so file.

 I am now trying an install from source, but when I run the command '$
rake ext' I get the following error when it reaches the 'make' command:

make
rake aborted!
Command failed with status (127): [make]

 This is slightly lost on me as I am a Ruby newbie, hopefully someone
will be able to tell me what is going on.

Thanks.
