dynamic library not found

running a python script that just imports sage.all I get this error:

// ** Could not find dynamic library: p_Procs_FieldQ.so (path /usr/lib/../lib/singular/MOD:/home/user/Documents/code/sage/sage/local/libexec/singular/MOD)
// ** Error message from system: /usr/lib/../lib/singular/MOD/p_Procs_FieldQ.so: undefined symbol: _Z8nlIsZeroP7snumberP9n_Procs_s
// ** Singular will work properly, but much slower.
// ** See the INSTALL section in the Singular manual for details.

And indeed that library seems to have plenty of undefined symbols:

$ nm -u ~/Documents/code/sage/sage/local/libexec/singular/MOD/p_Procs_FieldQ.so
                 w __cxa_finalize@@GLIBC_2.2.5

                 U _Z8nlIsZeroP7snumberP9n_Procs_s

This is against a freshly cloned git version. Is this some environment variable that I need to set or some part of Singular that I am missing?
