Perhaps someone has used your approach and has a forthcoming solution for you.  In the absence of that solution I can tell you that I get the development sources for Emacs using Bazaar (see the EmacsWiki for copious details) on a regular basis, build it and use it on Lion as a matter of course, as, apparently, do many others.  If you follow one of the EmacsWiki approaches and run into difficulties, you might get more joy from this, or some other, list.<div>

&gt; Hi!<br>
&gt;<br>
&gt; I have Mac OS X 10.7.4 and Emacs from git sources(through homebrew). When I open any file I got screen bugs <a href="http://cl.ly/1G1R2E0H2b0F2N1V1H1Y" target="_blank">http://cl.ly/1G1R2E0H2b0F2N1V1H1Y</a><br>
&gt;<br>
&gt; Any ideas what is this?<br>
&gt;<br>
&gt; Thank you.<br>
