I'm guessing you don't have write permission on /

No - I can write to '/' ok. The aim is to install perl-5.10 into /home/Rob so that it doesn't interfere with the existing 5.8.8 installation (which I'd still like to keep). If I drop the '-Dprefix' arg, the error I get is still the same.

I'll take a look through the makefile and see if I can spot something. It would be handy to have a 64-bit-int build of perl-5.10 on this Windows box, but I *can* live without it, so I won't be getting too stressed.

Update: I think I've found a (tedious) solution to my problem. It's just a matter of cd'ing to the ext/DynaLoader folder and running 'make -i', then when that terminates, return to the top level folder and re-run 'make'. Shortly thereafter the process terminates with a similar error regarding the ext/B directory ... so cd to ext/B, run 'make -i', then cd back to the top level and re-run 'make' .... and on it goes until the next failure in ext/somewhere ... etc., etc.

Update2: Duh .... wouldn't it be better to just run 'make -i' from the top level folder ? That's exactly what I'm doing now - but I won't really know how successful it has been until I get to run 'make test'.

Update3: Sort of nearly almost works ... many of the pm files in ext don't get copied across to lib. All in all, it's not a very good approach to be taking :-)

Cheers,
Rob
