Thanks Peter. That solved my problem.

As a rule, they shouldn't be doing that at all (unless as a side effect
of calling pkg-configure); one might have several versions of a library
installed, under different prefixes (a more recent or customized one
might be installed under my homedir, for example).  You don't want an
egg to go choosing the wrong one on its own accord.

Cheers,
Peter

Yeah, sorry this is pretty inconsistent. There are a couple of eggs
that will add /usr/local as a prefix for the linker and preprocessor.
However adding  the CSC_OPTIONS yourself is the best way.

Hi David,

I've used BSD in the past, and building an egg to look in the correct
location on NetBSD was a matter of calling chicken-install with
CSC_OPTIONS in the environment to set the C options, like

CSC_OPTIONS='-C -I/usr/include/blabla' chicken-install eggname

Hope this helps!

Cheers,
Peter
