small modification for 64-bit openSUSE

[Werner F. <wer...@uf...>]

Hi everyone,

just joined the list... I tried to build the package for openSUSE 11.4
x86_64, but configure complained that sftp-server was not found.

This is due to the directory naming convention on openSUSE systems. The
64-bit libraries are in /lib64, /usr/lib64, and so on. The configure
script searches them in /lib and /usr/lib only.

So I attach a diff file that might be applied as a a patch to configure.ac.

BTW, thanks for this package - simple to use and very effective!

Regards,
Werner
