As I had the same problem and it took me a while to figure everything  
out, here's the verbose answer:

$> apt-get install git-core

in your CVS tree go to lib/ and remove the X11/ directory. then  
check out libX11 from git.

$> git clone git://
$> mv libX11 X11

by renaming the directory to X11/ the script will build it.
libX11 is dependent on xcb which you need as well.

Then you need XCB, which is in git as well.

$> git clone git://
$> apt-get install check		 #otherwise you have to mangle with xcb's  
configure scripts

$> cd xcb-proto
$> ./ --prefix=<wherever>
$> make
$> make install

$> export PKG_CONFIG_PATH=<wherever>/lib/pkgconfig
$> cd xcb
$> ./ --prefix=<wherever>
$> make
$> make install

Now you should be able the util/modular/ script. My machine  
is still compiling but it seems to have gotten past the libX11 problem.
