Build problem (./configure fails) on BSD system

I'm trying to ./configure tin on a BSD system.

'uname -a' returns "OpenBSD leary2.csoft.net 3.8 GENERIC#247 amd64",
it's not my own system, just a system where I have a shell account.

The ./configure fails almost at the first hurdle:-

    ./configure --prefix=$HOME --enable-nntp-only
    loading cache ./config.cache
    checking for X... ./configure[846]: cd: conftestdir: bad directory
    libraries /usr/X11R6/lib, headers /usr/X11R6/include
    configure: error: can not find install-sh or install.sh in . ./..  ./../..

I've run other ./configure scripts on this system (well, one other)
with no problems so is there a workaround for this tin problem?
