Unable to compile GCC-4.4.3, Pass 1

Thanks for the reply. I've spent a lot of time in chapters 4 and 5.
I'm finding the book (6.6) a little unclear in certain areas which is
probably what is throwing me off to some degree.
For example, look at 5.5.1, first box. It says:
tar -jxf ../mpfr-2.4.2.tar.bz2
mv -v mpfr-2.4.2 mpfr
tar -jxf ../gmp-5.0.0.tar.bz2
mv -v ../gmp-5.0.0 gmp
What is the point of reference for "../pkg-name"? If I am in my
/mnt/lfs/sources dir, then the ../ takes me up to /mnt/lfs and the
source tarball is not there.
I haven't found any reference as to where I should be sitting
(directory wise...) when I issue the commands.

Page 5.5.1 *DOES* say exactly that:
"The GCC documentation recommends building GCC outside of the source
directory in a dedicated build directory."
Then in the next box:
mkdir -v ../gcc-build
The line above the first box states that GCC requires GMP and MPFR.
Now, if mpfr and gmp are unpacked in /mnt/lfs/sources, GCC has no
access to them. The only way I could get GCC to do anything was to
move both pkgs into /mnt/lfs/gcc-build/gcc-4.4.3/. But I am concerned

Correct, but that is contrary to the instructions.

I've tried so many different things trying to get this to work that I
will go back and rebuild the environment again. I don't believe I
have had any permission problems, but I will backtrack just to be sure

Funny thing... during my last attempt (which I used to get the
messages for this posting) I did forget the --prefix.

I'll check the prereqs again and rebuild the environment (again.... :)
I've gone back and forth over chapters 4 and 5 so often that I can
almost quote them. But obviously, I am missing something either
conceptually or I am mis-interpreting something.

Yeah, but I included it for completeness....
