MadGraph install

Download the file: MadGraph_v4.tar.gz, then make.
In my case, there appeared error message concerning to g77.

A1) g77 does not exists, thus replace g77 by gfortran:
# cd usr/bin
# ln -s gfortran g77
A2) still erorr occured saying something with "-i4" option for g77 in
the MadGraphII directory. Thus
# cd MG_ME_V4.4.27/MadGraphII
# less makefile
find the secodn line: "FFLAGS= -O -i4 -ffixed-line-length-132"
I deleted -i4 option, and it worked somehow.

B1)To see the plots, install MadAnalysis under the MG_ME_V4.4.27.
Then I went to the wiki-page and downloaded compiled version of td,
and placed it as follows; MG_ME/V4.4.26/td/td (this is must to makefile work). Remember to add executable by chmod +x td.
B2) Then make again with makefile under MG_ME_V4.4.27
