>Description:
lftp 3.2.1 installs fine with pkgsrc, but when running lftp, i get:

$ lftp                                                                        ~
lftp :~> open localhost
dlopen(/usr/pkg/lib/lftp/3.2.1/proto-ftp.so, 10): Symbol not found: 
__ZN6SMTask6ResumeEv
  Referenced from: /usr/pkg/lib/lftp/3.2.1/liblftp-network.dylib
  Expected in: flat namespace

open: ftp - not supported protocol
lftp :~> open sftp://localhost
dlopen(/usr/pkg/lib/lftp/3.2.1/proto-sftp.so, 10): Symbol not found: 
__ZN6SMTask6ResumeEv
  Referenced from: /usr/pkg/lib/lftp/3.2.1/liblftp-network.dylib
  Expected in: flat namespace

open: sftp - not supported protocol

There are two problems, probably related: 
in /usr/pkg/lib/lftp/3.2.1/ i have liblftp-network.dylib and liblftp-pty.dylib, 
and some .so files (as listed in PLIST)
those .dylib files cause problem when unintalling lftp too, since pkg_delete 
expects them to be ".so".
I tried to understand why libtool produces .dylib and .so files, but they seem 
to be installed exactly with the same libtool call, so i'm a bit lost

>How-To-Repeat:
Install lftp under tiger (the problem arise probably with other darwin 
versions).
Try to run it: it fails
try to deinstall it:
$ bmake deinstall                                          /usr/pkgsrc/net/lftp
===> Deinstalling for lftp
===> Becoming root%bonzai.local@localhost to deinstall lftp.

Running /usr/pkg/sbin/pkg_delete -K /usr/pkg/pkgdb lftp-3.2.1
pkg_delete: unable to completely remove directory '/usr/pkg/lib/lftp/3.2.1'
pkg_delete: unable to completely remove directory '/usr/pkg/lib/lftp'
pkg_delete: couldn't entirely delete package `lftp-3.2.1'
(perhaps the packing list is incorrectly specified?)

(i used the standard options, so built with gnutls and not ssl)
