Comment 4 for bug 432753

Allrighty ...

The new source tarball does not ship with .mozconfig file! Oops!!!
Also, the problem referenced all over the web:

configure: error: --enable-application=APP is required
*** Fix above errors and then restart with "make -f client.mk build

is caused by failure to add things to the .mozconfig file. Let's
be clear: The 0.7.10 build did not apparently require the two lines
given below?

5. Manually patch .mozconfig file

Copy the .mozconfig file from your old 0.7.10 source directory. (Note:
If you followed my directions above, then you will already have the file)

For the kompozer build, you must add these lines to the .mozconfig file:

ac_add_options --enable-application=composer
ac_add_options --enable-debug

6. NOW: make -f client.mk build_all

and the build starts .... and breaks

Another problem is that cairo dependency thing, also talked about all over the
web. This following workaround will get you there: Add this line to .mozconfig

ac_add_options --enable-system-cairo
