Ubuntu Tool-Building Blues

[Robert S. Grimes]

I'm trying to set up a build environment for testing the 4.9 branch on 
Ubuntu Linux, and I'm having a few problems.

1. I had hoped to use the prebuilt RPMs, but it seems Ubuntu is not 
supported :-( .  So I must build them myself, right?

2. Because I've been using 4.8, and need to update to use Sebastian's 
spi-sd-card driver - as well as possibly the nvdisk with FRAM), and am 
thinking of the future, I thought I'd try to build the 4.10 tools in 
/ftp/pub/rtems/SOURCES/4.10 - is that a good idea, or should I use 4.9?

3. I got binutils-2.18.tar.bz2, unpacked and patched it, confugiured a 
build directory, and am trying to build.  It failed, suggesting I 
install texinfo (though that was just a warning).  After installing 
texinfo, it still fails at the same place, and I can't seem to see the 
error.  Here is the complete output:

WARNING: `makeinfo' is missing on your system.  You should only need it if
         you modified a `.texi' or `.texinfo' file, or any other file
         indirectly affecting the aspect of the manual.  The spurious
         call might also be the consequence of using a buggy `make' (AIX,
         DU, IRIX).  You might want to install the `Texinfo' package or
         the `GNU make' package.  Grab either from any GNU archive site.

Any ideas?
