i don't undertstand these warnings.

to fix the lt_dlpreload_default problem probably requires that you
determine whether or not that symbol is available in the libltdl
installed on your system.  i don't know how to go about that remotely,
but if you give me an account on your machine i can try to look into it.
(ping me off-list if you are amenable.  same goes for any osx users
reading this.  gpg key: <http://www.glug.org/people/ttn/gpg-key.txt>)

to fix the "environ" problem, change the naked "extern char **environ;"
in posix.c to read like so:

#ifdef __APPLE__
#include <crt_externs.h>
__private_extern__ char **environ;
#else
extern char **environ;
#endif

you can hint the guile-w/-fink maintainer to look at:

 http://www.glug.org/snap/core-1-4/libguile/posix.c

where one can see this change applied in guile-1.4.x (in cvs), including
an informative comment by Aurelien Chanudet.  also fyi, this change made
it into guile 1.4.1.97, available at: <http://www.glug.org/alt/>.  since
you are already brave enough to build from source, i recommend grabbing
1.4.1.97 and giving it a try.  IIRC there are some other osx-specific
modifications already applied in that version.
