+1. Qt/Mac Free Edition, version 4. This library is GPL-licensed
+and can be downloaded from
+<http://www.trolltech.com/download/qt/mac.html>. You will need to
+compile it yourself (as described below).
+
+2. automake, version 1.9 or higher (check with automake --version).
+Probably the easiest way to get this is to use DarwinPorts (from
+http://darwinports.opendarwin.org/getdp/) and install automake
+using
+ sudo port install automake
+
+3. gettext version >= 0.12 (check with gettext --version)
+If the installed version is insufficient the
+easiest way to obtain a later version is to get DarwinPorts
+(from http://darwinports.opendarwin.org/getdp/) and install gettext
+using
+ sudo port install gettext
+
+
+BUILD INSTRUCTIONS
+
+Note that building LyX/Mac requires gcc version 4.0 or higher. (You
+can check your version by entering "gcc -v" in the Terminal; you
+can change your gcc version to version 4.0, for example, by entering
+"sudo gcc_select 4.0".)
+
+1. Create a directory where you want to install QT4. In the following,
+the full path to this directory is called /path/to/QT4
+Decompress Qt/Mac in a convenient directory, cd to the top of the
+Qt source hierarcy, and:
+
+ ./configure -static -no-exceptions -nomake examples -nomake tools -prefix /path/to/QT4
