CTFE with C functions not possible?

To be more explicit, I wrote a library in C since it's much leaner size-wise 
than the D code (although admittedly much *much* more tedious to write 
especially with all those string manipulations) and since it's callable from 
other languages like Python too.

None of those other languages have CTFE AFAICS. I would like to provide at 
least the D wrapper to the C library with a template which will enable CTFE 
computation via the library (it's just a string to string conversion). But 
the D compiler is complaining that it cannot call the C function at compile 
time even though the library is installed under /usr/local/lib and Python is 
able to access it via CTypes.

Please help!
