make install fails on OS X due to non-portable install -D flag

[fletort]

sudo make install install -D -m644 libmpsse.so //usr/local/lib/libmpsse.so install: illegal option -- D usage: install [-bCcpSsv] [-B suffix] [-f flags] [-g group] [-m mode] [-o owner] file1 file2 install [-bCcpSsv] [-B suffix] [-f flags] [-g group] [-m mode] [-o owner] file1 ... fileN directory install -d [-v] [-g group] [-m mode] [-o owner] directory ... make: *** [install] Error 64

==> -D is a GNU extension of the install program, not available in the BSD version of install that ships on OS X.
