Hi, I've noticed that when I install libxml2, the header files aren't linked in to /usr/local/include. Is that expected? [aaron@higgins /]$ ls /usr/local/Cellar/libxml2/2.7.8/include/libxml2 libxml [aaron@higgins /]$ ls /usr/local/include/libxml2 ls: /usr/local/include/libxml2: No such file or directory [aaron@higgins /]$ Thanks! -- Aaron Patterson http://tenderlovemaking.com/
It would appear so. This is the message from the installer:
==> Caveats
This formula is keg-only, so it was not symlinked into /usr/local.
Mac OS X already provides this program and installing another version in
parallel can cause all kinds of trouble.
Generally there are no consequences of this for you.
If you build your own software and it requires this formula, you'll need
to add its lib & include paths to your build variables:
LDFLAGS -L/usr/local/Cellar/libxml2/2.7.8/lib
CPPFLAGS -I/usr/local/Cellar/libxml2/2.7.8/include

The extconf.rb in nokogiri looks in common places for libxml2 (/usr/local, /opt/local, /usr). Since this formula became keg only, it's a PITA for people to install nokogiri and use libxml2 from homebrew. If there was a consistent path I could search, then I could add that to the extconf. For now we have instructions specific for homebrew users, but it would be great if we could make it "Just Work" for homebrew users too! Thanks. -- Aaron Patterson http://tenderlovemaking.com/

I think the `brew --prefix` command would work perfectly. We can figure out the paths in the extconf and search them (if brew is installed).
