FC6 + source for Nvu build help

[linuxmaillists at charter.net]

This is my first time attempting to build from source.  
Below are the instructions for building Nvu from source.  I 
am doing this as root.

Building Nvu From Source
Nvu 1.0

If you want to build Nvu from the source, please following 
these directions.

   1. First read and follow the build instructions for your 
platform. If you want to build on Windows, make sure to 
download bzip2 with Cygwin.

Did, don't think there was a problem

   2. Get the sources and save them on your disk

Did no problem

   3. Uncompress-untar the sources

      tar xfj nvu-1.0-sources.tar.bz2

Did no problem

      This creates a directory called mozilla
   4. Go into the directory mozilla/composer/config , grab 
your preferred mozconfig.* file and copy it to 
mozilla/.mozconfig (dot mozconfig in the top mozilla 
directory). Edit that file according to your wishes and 
system configuration. Warning: the mozilla/composer/config 
also contains a compressed patch against the Firefox 1.0 
source tree: you don't have to apply that patch to the 
source tarball linked above, it's already in.

Did no problem

   5. Build the code.

      make -f client.mk build_all

Did and got an error after about a minute of activity.  Here 
are the last several lines:

nsStackFrameUnix.cpp: In function ‘void 
DumpStackToFile(FILE*)’:
nsStackFrameUnix.cpp:96: error: ‘JB_BP’ was not declared in 
this scope
gmake[4]: *** [nsStackFrameUnix.o] Error 1
gmake[4]: Leaving directory `/home/user/mozilla/xpcom/base'

make[1]: *** [default] Error 2
make[1]: Leaving directory `/home/user/mozilla'
make: *** [build] Error 2

I replaced above the real user name with user

How can I find out what went wrong?  What did I miss?


   6. After the build, there is in the mozilla/dist/bin 
(Linux) or mozilla\dist\bin (Windows) directory a file 
called nvu or nvu.exe. Just run it to start Nvu.  On Mac, 
just double-click on mozilla/dist/Nvu.app. Don't forget to 
look at the Tips and Hints section at the bottom of this 
page.
