Recently I have been describing my troubles installing gfortran in the
comp.lang.fortran newsgroup, and FX has given useful help. But today
my system won't let me read anything in that newsgroup so I'm emailing
to you.
One thing that wasn't suggested but I find allowed me to configure GCC,
make and make install was rm -f /tmp/gccobj/prev-* before starting.
(I used a bash shell script saying inter alia
srcdir=/tmp/gcc-4.6.2
objdir=/tmp/gccobj
prefix=/tmp/gf
target="i686-pc-linux-gnu"
gccopts=" --prefix=$prefix --enable-languages=c,c++,fortran"
gccopts=$gccopts" --disable-libada" # unlikely to need ADA!
gccopts=$gccopts" --with-gmp=$HOME --with-mpfr-include=$HOME/mpfr-3.0.0"
gccopts=$gccopts" --with-mpfr-lib=$HOME/mpfr-3.0.0/.libs"
gccopts=$gccopts" --with-mpc=$HOME/mpc-0.9"
$srcdir/configure $gccopts # http://gcc.gnu.org/install/configure.html
because my HOME disk space is too small for GCC and all the things it
needs. I then copied /tmp/gccobj/gcc/gfortran to /tmp/gf/bin/gfortran
and /tmp/gccobj/gcc/f951 to
/tmp/gf/libexec/gcc/i686-pc-linux-gnu/4.6.2/f951
My little test program then compiled but wouldn't run even though the
library said to be missing does exist. It was presumably put somewhere
that gfortran couldn't find it. What should I do now? Evidence:

In my reply directing you to the gcc-help list I also answered your
question, I guess you didn't scroll down far enough :)
I said:
The dynamic linker needs to know how to find the library at run time.

Thank you - after many, many unsuccessful tries I have at last got
a working gfortran 4.6.2! As will be obvious, I am an extreme newbie as
a systems programmer. One question I have is that our systems people
installed gfortran 4.4.4 and when I use it with -v I get inter alia
Target: i386-redhat-linux6E
but when I installed gfortran 4.6.2 myself on the same machine without
specifying --target I get
Target: i686-pc-linux-gnu
Why the difference? FWIW the command set | grep 86 gives
HOSTTYPE=i386
MACH=i386
MACHTYPE=i386-redhat-linux-gnu

See http://airs.com/ian/configure/configure_4.html for info on
configuration triplets. The differences would be more significant if
you were looking at an x86 GNU/Linux machine and e.g.
sparc64-sun-solaris2.10, but for two different triplets for an x86
there isn't a lot of difference.
The "pc" versus "redhat" manufacturer field is not usually used, it's
just descriptive.
Since GCC 4.5 the default instruction set generated by GCC on x86
depends on the machine type it is configured for, so for the GCC 4.4
installation the "i386" is merely descriptive, and of "i386", "i486",
"pentium2" etc would have been equivalent, but for GCC 4.6 it means
that GCC will generate code that assumes it will run on an i686 (or
later). See http://gcc.gnu.org/onlinedocs/gcc/i386-and-x86_002d64-Options.html
for details of how to override the default machine type with -march
option.
I don't think "linux6E" vs "linux-gnu" matters either, I think
configure scripts match on linux*
