[Box Backup] Error in install scripts in 0.09_plus2?

[Pascal Lalonde]

The {$exec_prefix} variables in install-backup-server and
install-backup-client are not substitued once the build is over. I tried
this on OpenBSD and Linux.

Doing a "make install-backup-{client,server}" copies the executables to
{$exec_prefix}/bin, thus to /bin.

Also, the parcel names are wrong under OpenBSD:
boxbackup-0.09_plus2-backup-client-openbsd3.838
instead of:
boxbackup-0.09_plus2-backup-client-openbsd3.8

I build using:
./configure
make
make install-backup-server
make install-backup-client

Am I doing something wrong?
