guile can't find dynamically loaded library

[Michael Vanier]

Hi,

I've been walking through the guile info documentation, specifically the
section on defining your own guile extensions.  This is for guile-1.6
running on a Debian GNU/Linux system.  I am unable to get guile to find the
location of the shared library that I created (libguile-bessel.so).  I have
tried everything I can think of.  I have put the file into /usr/lib and it
still couldn't find it!  I setenv'd LTDL_LIBRARY_PATH to the current
directory; no dice (is LTDL a misprint?).  I always get the following
message:

guile> (load-extension "libguile-bessel" "init_bessel")
standard input:1:1: In procedure dynamic-link in expression (load-extension 
"libguile-bessel" "init_bessel"):
standard input:1:1: file: "libguile-bessel", message: "file not found"
ABORT: (misc-error)

Type "(backtrace)" to get more information or "(debug)" to enter the debugger.
guile> 

I suspect that the documentation is incorrect.  Can you clarify what's
needed to inform guile of where a shared library is?
