Hello Leo,

I am sorry for this delayed response!

In the initial version of this description, I have put the auxiliary 
scripts in /scripts/.

I didn't know that all auxiliary scripts should be put in 
/share/name_of_package/scripts.

The script loads the package using a relative path.

Ludo corrected my description and changed my substitute lines to this,

-                 (wrap-program (string-append out "/scripts/histogram.py")
+                 (wrap-program (string-append out
+                                              "/share/filtlong/scripts/histogram.py")

Now the script is on the right place 
(/share/filtlong/scripts/histogram.py), but it does not contain the 
right relative path. So, this patch is needed to correct the relative path.

+               (substitute* "scripts/read_info_histograms.sh"
+                (("/../") "/../../../"))

Sorry, from the beginning was my mistake!
