I ran nmake install >install.txt to give you some details. As I suspected most of it is copying to the source folder. If anyone can tell me why they'll get a medal.

Thanks for the pointer. As I suspected it's going into the source folder. Here are a few exerts:-

    ..\miniperl.exe -I..\lib buildext.pl nmake -nologo perldll.def ..\
+ext<br>
Making B<br>
nmake -nologo<br>
    ..\..\miniperl.exe "-I..\..\lib" "-I..\..\lib" -MExtUtils::Command
+ -e cp bin/piconv blib\script\piconv<br>
    cd ..\pod<br>
    copy ..\vms\perlvms.pod .\perlvms.pod<br>
    cd ..\win32<br>
    ..\perl.exe bin\pl2bat.pl ..\utils\h2ph         ..\utils\splain   
+      ..\utils\dprofpp     ..\utils\perlbug     ..\utils\pl2pm       
+   ..\utils\c2ph<br>
xcopy /f /r /i /d bin\*.bat c:\perlc\bin\*.*<br>
0 File(s) copied<br>
    ..\perl.exe -I..\lib ..\installhtml --podroot=.. --htmldir=./html 
+ --podpath=pod:lib:ext:utils --htmlroot="file://c|\perlc\html"  --lib
+pod=perlfunc:perlguts:perlvar:perlrun:perlop --recurse
    xcopy /f /r /i /e /d html\*.* c:\perlc\html\*.*<br>
0 File(s) copied

It's not till the end that it actually starts putting things in the right place. What file do I need to edit to get it all going in the right place? In my Makefile I have:-
INST_DRV = c:
INST_TOP = $(INST_DRV)\perlc

Any clues would be great.
