Now, as the root user:
make install
--enable-unicode-properties: This
switch enables Unicode properties support and includes the code for

switch enables 16 bit character support.
--enable-pcre32: This
switch enables 32 bit character support.
--enable-pcregrep-libz:
This switch adds support to pcregrep to read .gz compressed files.
--enable-pcregrep-libbz2:
This switch adds support to pcregrep to read .bz2 compressed files.
--enable-pcretest-libreadline: This
switch adds line editing and history features to pcretest program.
--disable-static: This
switch prevents installation of static versions of the libraries.
--enable-jit: this option enables
Just-in-time compiling, which can greatly speed up pattern
matching.
