HI Guys,

I am trying to install ferret as a gem ‘sudo gem install ferret’ and it  
is  
failing  
to make the native libraries, I am using the 64 bit version of Ubuntu  
7.10

Here is the first the first 30 lines or so, any hints, I know it is  
probably  
some sort of 32 bit v 64 bit problem??

You seem to be missing the C library development package. Try installing  
glibc.
