/usr/bin/file, produces output that libtool cannot recognize

[Daniel Rucci]

hi i was configuring something on my FreeBSD 5.4-RELEASE-p1 box and 
libtool told me to contact you. so i did.

*** Warning: the command libtool uses to detect shared libraries,
*** /usr/bin/file, produces output that libtool cannot recognize.
*** The result is that libtool may fail to recognize shared libraries
*** as such.  This will affect the creation of libtool libraries that
*** depend on shared libraries, but programs linked with such libtool
*** libraries will work regardless of this problem.  Nevertheless, you
*** may want to report the problem to your system manager and/or to
*** address@hidden

is the warning

i have libtool(ize)15 and would be happy to give you any further 
information you need about my setup.

Thanks,
