To install !BlackHat follow the following steps:

- install the depedencies

qd:

install qd from the webpage http://crd.lbl.gov/~dhbailey/mpdist

{{{
wget http://crd.lbl.gov/~dhbailey/mpdist/qd-2.3.13.tar.gz
}}}
and install the package. Use the configure options:

{{{
--enable-shared
}}}

Make sure the shared libraries are installed. When building qd is looking for other compilers than g++ and is seems that depending on which it finds the shared library will not be supported,  so I found that one sometimes had to specify t use g++ with the additional argument CXX=g++ (or another compiler which supports shared libraries) in the configure command line. 

2. download the BlackHat tar ball, unzip and unpack:

{{{
wget http:///whereever 
tar -xzf blackhat-1.0.0.tar.gz
cd blackhat-1.0.0
}}}

Configure, the options (in addition to the usual options such as --prefix) are the following:
{{{
  --with-QDpath=prefix    try this for a non-standard install prefix of the QD
                          library
  --enable-sherpaplugin    compiles the BH sherpa plugin
  --enable-pythoninterface    compiles the python interface
}}}

Install the data files. 

Download the files from /Where do we put them?/ and install them using the script that gets installed along with the library 

{{{
wget WHERE.EVER all.tar.gz
dataInstall all.tar.gz
}}}
