Had a brain wave this evening and came up with the following solution.
Replace /usr/lib/perl5 with /usr/local/.p5 in the perl binary[1]. Then
create a symlink from /usr/local/.p5 to /usr/local/lib/perl5. The .p5
directory doesn't display in /usr/local so everything looks neat and tidy.
I am then left with the whole perl installation entirely contained in
/usr/local which means I can remove the Compact Flash card (containing perl)
without leaving any loose ends lying around in the main filesystem of my
iPAQ.
The next challenge will be getting gcc onto the iPAQ so that I can then
rebuild perl from scratch :)

[1] Strangely enough, perl came in pretty handy for this task.
