1.5.2 installation issue on Ubuntu 11.10

[Edwin]

As part of the Ruby on Rails Tutorial, I tried installing Nokogiri
1.5.2 on Ubuntu 11.10. However, I keep getting the message that I do
not have libxslt installed, even though I have installed all the
libraries shown by `rvm requirements`. (I also manually ran `sudo apt-
get install libxslt-dev libxslt1-dev`, but got the same results.
Ubuntu's apt-get cannot find libxslt, though.) I double checked to
make sure that the 64-bit version of libxslt was installed, so I know
the issue isn't there.

What do I need to do? Relevant details are below.

Quick overview of my environment:
OS: Ubuntu 11.10 x86_64
Ruby: 1.9.3p125 w/ openssl & iconv
Rubygems: 1.8.21
RVM: 1.12.1

Shell output:

$ gem install nokogiri -v '1.5.2'

ERROR: Error installing nokogiri:

Did you visit this page for help with installing dependencies? My hunch is that you have not yet installed libxslt-dev.

As John Barnette said once, "Isn't package management convenient?"

Thanks for using Nokogiri.

Yes, I did, unless the package is explicity called as libxslt-dev. Apt-
get, for some reason, always autoselects libxslt1-dev whenever I run
sudo apt-get install libxslt-dev.

If it helps, here's the mkmf.log file for the error.
