While leafnode can currently be built without the PCRE library installed
(it will build a static version then), it is better if you go to the
pcre/ directory first and build and install PCRE as a shared
library. This saves memory.

Do

cd pcre && ( make distclean ; ./configure && make \
&& su -c "make install" )

Note however that on some systems, you must invoke ldconfig after make
install.
