I haven't looked into details of this particular package, but in general 
unmangling rarely helps curing FTBFS due to missing symbols. The C++ 
mangling rules are (mostly?) architecture-idependent. What does vary 
with architecture are how various types (size_t, intN_t, va_list, etc.) 
are typedefed. But demangling doesn't help dealing with this variation.

For example, symbol names for a f(size_t) function are:
_Z1fj on i386,
_Z1fm on amd64.

After unmangling it becomes:
f(unsigned int) on i386,
f(unsigned long) on amd64.
