make install tries to install perl files in other locations than provided with --prefix

[Trond Norbye]

I run ./configure --prefix=/opt/subunit but when I try to run make install it fails due to permission problems installing files into /usr/perl5.

trond@storm> gmake install
gmake -C perl all

I'm not sure whats causing this; patches would be great. I know for me that it seems to work.
