You need to pull some other software
the Boehm GC and PCRE libraries:
On Fedora: yum install gc gc-devel
On Ubuntu (or other debian distros): apt-get install libgc-dev libpcre++-dev
This just need to build and install this. Note: You should enable the gc garbage collector (it's an option in the Makefile, or provide as an option to make:
git clone git://github.com/jplevyak/dparser.git (cd dparser; sudo make install D_USE_GC=1)
This is expected to exist in ../plib.
git clone git://github.com/jplevyak/plib.git (cd plib; make USE_GC=1)
This is expected to exist in ../ifa.
git clone git://github.com/jplevyak/ifa.git (cd ifa; make)
