Similar but different result for another gem:


thufir@dur:~$ 
thufir@dur:~$ 
thufir@dur:~$ whereis curl
curl: /usr/bin/curl /usr/share/man/man1/curl.1.gz
thufir@dur:~$ 
thufir@dur:~$ gem install feedzirra  --no-rdoc --no-ri
Building native extensions.  This could take a while...

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:
	--with-opt-dir
	--with-opt-include
	--without-opt-include=${opt-dir}/include
	--with-opt-lib
	--without-opt-lib=${opt-dir}/lib

	--with-curllib
	--without-curllib
extconf.rb:23:in `<main>':   Can't find libcurl or curl/curl.h

  Try passing --with-curl-dir or --with-curl-lib and --with-curl-include
  options to extconf.

Sigh.  Do I have to re-install ruby or something?  Or are these gems the 
problem?  Seems more likely that my computer is, though.
