Cannot install SRFI-207 egg

[Jeronimo Pellegrini]

Hello,

with the latest checkout from git
(41a1decf5762c1178a9da2250df39a28badbb736)

I get unbound variable: ##sys#core-library-modules:


chicken-install srfi-207

Since the latest commit seems to be related to that, I tried the
previous one (1ab4f97722d8e8d829f2cc8fa08696c94bbbed8e), but got the
same error.

Am I missing something? Some dependency?

Thanks,
J.
