OK if the .pyx source is installed (we currently package it separately in

That makes sense to me. cached_method wraps a method, i.e., it replaces
it by something different. In order to make various things work, some
form of introspection is needed---which for cython extension code is
difficult if the source code cannot be found.
I could try to make some experiments (e.g., create a cython module with
a cached method, recompile sage, and then remove the source of the
module) in order to find out if there is a way around (and if I can
replicate the problem).
Never had that problem in sage-on-gentoo but then I am always
installing the source as it is necessary to run the testsuite.
I'll have to see if it happens to end users that don't have the
"testsuite" flag on.
