My little test program then compiled but wouldn't run even though the

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
