Hello
I tried to attach a Cython file that worked in previous versions of Sage
(incl Sage beta 6.4.1) to Sage beta 6.5.1, but it fails:
sage: %attach dynamic_algorithm_with_skeleton.pyx
Compiling ./dynamic_algorithm_with_skeleton.pyx...
Error compiling cython file:

compilation terminated.
error: command 'gcc' failed with exit status 1
The Cython file includes the lines (thanks for the help with this a year or
two ago!)
# cinclude $SAGE_ROOT/local/include/singular
# clib m readline singular givaro gmpxx gmp
I don't *think* I need gmp anymore, so I removed gmp and gmpxx... only to
encounter the same error.
Apparently this looks like an error with Singular that Sage has encountered
before (here
<https://groups.google.com/d/topic/sage-support/ddf-v16fpi8/discussion>,
here <https://groups.google.com/d/topic/sage-support/YHSYGvxR1Eg/discussion>,
and here
<https://groups.google.com/d/topic/sage-support/ocnSDgngJLI/discussion>)
but the earlier problems were with building Sage from source. At least one
problem was fixed in ticket #14737 <http://trac.sagemath.org/ticket/14737>.
Has this error returned, or am I doing something wrong?
