Comment:
I was trying to make it crosscompile, but it first warns that `configure: WARNING: Unable to find NTL (which is strongly recommended) on your machine` and then fails with
```
checking for dd_free_global_constants in -lcddgmp... no
configure: error: Error, could not use libcddgmp
```
Any ideas?
