On my develop branch for sage, whenever I attempt to build with ``sage
-br``, I get the following error message:
make: *** No rule to make target `sagelib-no-deps'. Stop.
What could be the cause of this issue? It happened all of the sudden after
I made a new local branch. This is on Sage
Thank you, luisfe, for this detailed reply!
Of course it would be formally nice to have the map
lambda x: x.map_coefficients(phi)
be an actual sage homomorphism (which it will always be if phi is a
homomorphism of coefficient rings). But for now what you propose works
fine for me.

Can you give some more info on what you did? Which commands did you issue?
Which patches did you install? Did you rebuild Sage after installing them?
Which Sage version?
Does your Sage have the matroids and Matroid keywords on startup?

The command I used which caused the error was from sage.matroids.all
import *. I added the matroids (I think this one worked) by using 'sage -hg
clone https://bitbucket.org/matroid/sage_matroids' and '../sage setup.py
install' from the shell prompt, but got the following errors on the
the sage
prompt:
syntax error near unexpected token `trac_14668_bitsets.patch'
That's weird, it looks like a Bash shell error. You are running Sage when
entering those commands, right? Can you show what (if anything) is posted
before the error? Should be something like
cd /Users/stefan/sage
You're not running sage. Start Sage first, then from the prompt looking like

Hello everyone,
I compiled and installed Sage 5.2 on my homeserver which worked fine and so the
commandline version did.
Then I tried to make sage available fom the Internet with notebook(). I found
some instructions about configuring apache, so access to Sage is carried
through an internal
dictionary? Also, is there any reason the above constructions don't
work, or are they simply not implemented yet?
Cheers,
Stefan.

expect that factoring

If I replace the definition of the ring R by
