Nonsense. First of all, developers aren't "the average user". Second, 
the inability of others doesn't make a programmer worse. And third, 
there are limits to what extend one can anticipate the ineptness of 
others to read. The page you cite from starts with:

   For special installation instructions regarding MS Windows and 
MacOS-X, see below.

And below you find this link:

   http://codespeak.net/lxml/build.html#building-lxml-on-macos-x

Which contains the proper command

   STATIC_DEPS=true sudo easy_install lxml
