Unpack a plain amber distribution

    tar xzf /sw/mcm/app/amber/amber8.tgz
    cd amber8

download the amber8 ramd-patch:

    wget http://projects.villa-bosch.de/mcmsoft/amberpatches/ramd/amber8-sander-ramd-0.2.patch.gz

unzip the RAMD patch:

    gunzip amber8-sander-ramd-0.2.patch.gz

apply the patch towards the amber distribution. Make sure your current
working directory is in the AMBERHOME directory:
 
    patch -p1 < amber8-sander-ramd-0.2.patch

Please make sure, you run the patch command on amber8 as distributed. If you apply the
patch a second time, there will be questions from the patch command.

If your current directory is not the AMBERHOME direcotory, apply the patch with

   patch -p1  -d $AMBERHOME < amber8-sander-ramd-0.2.patch

Then compile the amber executable according to the amber manual.

For the npsa patch add the option -F 3 and -p0:

   patch -F 3 -p0  -d $AMBERHOME < amber8-sander-npsa.patch
