As discussed [http://groups.google.com/group/sage-
devel/browse_thread/thread/9788a6ad6fe03ab9 here], the Python script
{{{$SAGE_ROOT/spkg/base/sage-make_relative}}} is run before Python is
built in Sage. On a system that do not have Python installed (like a fresh
install of IBM's AIX operating system), this generates an error message
message as this script is run.
{{{
Making Sage/Python scripts relocatable...
python: No such file or directory
}}}
This could be quite worrying, to find that an important program like
Python is missing.
The bottom of the file {{{$SAGE_ROOT/spkg/base/sage-spkg}}} has this:
{{{
echo "Making Sage/Python scripts relocatable..."
cd "$SAGE_LOCAL"/bin
./sage-make_relative
echo "Finished installing $PKG_NAME.spkg"
# It's OK if the above fails -- in fact it will until Python
# itself gets installed. That's fine.
exit 0
}}}
which indicates a failure of {{{sage-make_relative
}}} is unimportant. But still it is annoying and led me to believe there
was a more serious bug.
It does not seem appropriate to let {{{sage-make_relative
}}} fail, but it would be much better if {{{sage-make_relative
}}} can be removed, and its functionality moved to the script that calls
it, which is {{{$SAGE_ROOT/spkg/base/sage-spkg}}}
I've attached a copy of {{{$SAGE_ROOT/spkg/base/sage-make_relative}}},
which I believe could be written much better. I'm attaching it, since I
will want to create an external link to this file.
