OK, thanks.  I&#39;ve looked at that before and found that it sometimes returns empty, which I now presume means that the default path is sufficient, but previously thought that it wasn&#39;t always able to return an answer.   So I will eventually try to incorporate this into the grovel files.<br>

Dear gsll-dev,<br>
<br>
I was unable to build gsll (through quicklisp) on my gentoo box today<br>
because of &quot;missing ffi.h&quot;. After I filled a bug report* with gentoo<br>
they gave me the advice to use<br>
<br>
  pkg-config --cflags-only-I libffi<br>
<br>
to get the right path to ffi.<br>
<br>
I am able to build gsll anyway but maybe this &quot;tool&quot; is something that<br>
could be incorporated into the build of gsll.<br>
<br>
Cheers,<br>
Niklas<br>
