So did I.  Sorry, I skipped it in my post.  The first error is:

--%<---
[..]
/bin/sh: ./ctypesgen.py: Permission denied
make[1]: *** [OBJ.x86_64-unknown-linux-gnu/date.py] Error 126
make[1]: Leaving directory `/osgeo/src/grass7_trunk/lib/python/ctypes'
make: *** [default] Error 2

More upon this -- The partition I am running all this is mounted as

/dev/sda5               /osgeo          ext4            auto,rw,exec,user 0 2


Trying in fist place to execute "./confiure" or "./configure --help" 
wouldn't/wont do a thing. i.e.

--%<---
./configure --help

bash: ./configure: Permission denied
--->%---


Instructing, as I read somewhere (don't remember where!),  "sh ./configure --
help" works fine!  So, I think it is the same issue here too. For example,

--%<---
./osgeo/src/grass7_trunk/lib/python/ctypes $ ./ctypesgen.py

bash: ./ctypesgen.py: Permission denied
--->%--


So, in a similar way, instructing

--%<---
python ./ctypesgen.py

Error: No header files specified
--->%--

seems to work just fine.


My guess is that it's the same for all "Permission denied" errors.  I need to 
find a "global" solution and not going into handcrafting the scripts myself -- 
that wouldn't be the "right" way to do it.

--%<---
ls -lah g.html2man.py 

-rwxr-xr-x 1 nik users 1.1K Jul  7 10:24 g.html2man.py
--->%--

and "I" am in users,

--%<---
groups nik

wheel audio cdrom video users
--->%--

Hence, if I do

--%<---
python /osgeo/src/grass7_trunk/dist.x86_64-unknown-linux-
gnu/tools/g.html2man.py

Traceback (most recent call last):
  File "/osgeo/src/grass7_trunk/dist.x86_64-unknown-linux-

    main()
  File "/osgeo/src/grass7_trunk/dist.x86_64-unknown-linux-
gnu/tools/g.html2man.py", line 15, in main
    infile = sys.argv[1]

--->%--

it looks like it's going.

Yes, I don't repeat this (anymore, since long ago).  Trying to learn 
Gentoo/Funtoo :-)
