Mongrel users - Dec 2006 - unitinialized constant Mongrel::HttpHandler (NameError)

Using RailsLive CD (PCLinuxOS) installed to HD.

''gem install mongrel'' reported:
   Successfully installed mongrel-0.3.13.4.

though there is one error:
   make: ***
[/usr/lib/ruby/gems/1.8/gems/mongrel-0.3.13.4/lib/http11.so] Error 127

Google is no help for this one as the only reference to this error I 
could find suggested it might be solved by installing libc, for which I 
already have the newest version (glibc).

Help most welcome. For me no mongrel = no rails :-(
