------------------------------------------------------------------------+---
 Usually {{{PREFIX/lib/chicken/BINVERSION}}} exists when {{{write-info}}}
 is called, but there are certain corner cases (e.g., [http://wiki.call-
 cc.org/egg/setup-helper setup-helper] on cross environments) which make
 {{{write-info}}} fail on trying to write to a file in a directory which
 has not been created.

 The corner case triggered by setup-helper is that it doesn't contain any
 file to be installed on {{{PREFIX/lib/chicken/BINVERSION}}} besides the
 setup-info.

 The attached patch fixes the problem by making {{{write-info}}} call
 {{{ensure-directory}}} before actually writing the setup-info file.
