Current configure.in contain the following construct to fetch in-system
dmake version:
DMAKE_VERSION=`$DMAKE -V | $SED -n 's/.*Version \([[0-9.]]\+\).*/\1/p'`
The regexp is non-portable. The basic regular expressions has no +
construct (althougth some implementation may add it). The standardized
way to declare 1+ is \{1,\}
On the system where sed know no '+' extension the DMAKE version is not
extracted and DMAKE is claimed to be too old. The buildin dmake is
builded so the bug has no visible consequences.
Hope it help
