-1. Qt/Mac Free Edition, version 3.3. 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).
+Note: Only Qt/Mac is needed for building official LyX releases, and
+so steps 2 and 3 can be skipped in these cases. Those wanting to
+build developmental versions must have automake and gettext as
+well.
+
+1. Qt/Mac Opensource Edition, version 4. This library is GPL-
+licensed and can be downloaded from
+<http://trolltech.com/developer/downloads/qt/mac/>. To compile it,
+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 enter:
+
+ ./configure -static -no-exceptions -nomake examples -nomake tools -nomake demos -prefix /path/to/QT4
+ make
+ make install
+ cd /path/to/QT4/lib
+ rm *.la
+
+2. [Needed only for developmental builds:] automake, version 1.10
+or higher (check with automake --version). Probably the easiest
+way to get this is to use MacPorts (from http://www.macports.org/)
+and install automake using
+
+ sudo port install automake
+
+3. [Needed only for developmental builds:] gettext version >= 0.12
+(check with gettext --version). If the installed version is
+insufficient the easiest way to obtain a later version is to use
+MacPorts (from http://www.macports.org/) and install gettext
+using:
+
+ sudo port install gettext
+
+4. [Useful to simplify detection of Qt:] pkg-config >= 0.9.0. Again,
+the simplest way is through MacPorts:
+
+ sudo port install pkgconfig
