Undefined symbol "csin"

I've compiled sources of a C library which is then used by a python library.
Everything's ok at compile time but at runtime (of a python script using the 
python lib
and thus the shared lib compiled from the C source), it tries to load
the library I've compiled and failed with :

Traceback (most recent call last):
  File "lp", line 1, in ?
    from cvxopt.base import matrix
ImportError: /my/local/path/lib/python/cvxopt/base.so: Undefined symbol

        libc.so.6 => /lib/libc.so.6 (0x28077000)

Looking at headers in /usr/include and /usr/local/include, I didn't find any 
(math) header
with csin.
What am I missing ?
Are trigonometric functions on complex, implemented on freebsd ?
