No it won't, why do you say that (although please read below because I
realise that there is an error with my strtegy because of the possible
difference in USE flags)

That was not the question posed. The question assumed:
Machine A with updated portage and all updates emerged.
Machine B with poor network access, and its portage updated from Machine A
So both machines will have the same portage, but admittedly may not have
the same USE flags.
I think you are right in saying that the USE flag differences will cause
problems with my method. This is because:
1. Different USE flags may result in different dependencies for a given
package; and
2. Different USE flags may result in different download files even
within the same package.
OTOH your approach has problems in that not all files reside on gentoo
mirrors, some reside on sourceforge or other more obscure places.
IMHO my approach can be fixed by:
1. On machine B, as well as running:
emerge -uDp world|grep ebuild|awk '{print($4)}'>packlist
also run:
emerge info|grep USE |cut -d\" -f2 > B.uselist
2. On machine A, instead of running:
for package in `cat packlist` ; do DISTDIR="/where/ever/i/want"
GENTOO_MIRRORS="local
/usr/portage/distfiles" emerge --nodeps -f =$package; done
run:
for package in `cat packlist` ; do DISTDIR="/where/ever/i/want"
GENTOO_MIRRORS="local
/usr/portage/distfiles" USE="-* `cat B.uselist` emerge --nodeps -f
=$package; done
emerge will use the USE list from machine B, and will collect files
locally before grabbing them from the net.
Certainly, like most of linux, there is more than one way to do it. :-)
