[maemo-developers] Can't find lt_dlopen in autobuilder for DIABLO

[From: Bruce Forsberg]

I am trying to port the mp3splt package to DIABLO. I am have problems
getting the library package to build with the autobuilder. It does not
seem to be able to find the libltdl library. I have included libtool,
libltdl3, libltdl3-dev in the Build-Depends of the control file but
this does not seem to work as the configure file gives the error:

checking ltdl.h usability... no
checking ltdl.h presence... no
checking for ltdl.h... no
checking whether to use included libltdl...
.
.
.
checking for lt_dlopen in -lltdl... no
configure: error: libltdl not found - check libtool installation !

This all works in my scratchbox DIABLO_ARMEL environment. Does anybody
have any ideas on what I need to add to get this to work. I believe
that mp3splt uses plugins so I need this to work. The error files are
at:
https://garage.maemo.org/builder/diablo/libmp3splt_0.5.7a-maemo1/

The control file is (I have tried many combinations):
Source: libmp3splt
Priority: optional
Maintainer: Munteanu Alexandru Ionut (io_alex_2002 at yahoo.fr)
Build-Depends: debhelper (>= 5), libtool, libltdl3-dev, libvorbis-dev,
libmad0-dev, libid3tag0-dev, autotools-dev
Standards-Version: 3.6.0
Section: user/multimedia

Package: libmp3splt0
Section: libs
Architecture: any
Depends: libmp3splt
Description: Library that splits MP3 and Ogg Vorbis files without reencoding

 files into smaller files without decoding. Useful for splitting albums, either
 manually, using freedb.org data, or .cue files ...

Package: libmp3splt0-dev
Section: libdevel
Architecture: any
Depends: libmp3splt0
Description:  Library that splits MP3 and Ogg Vorbis files without reencoding
 Used to split MP3 (VBR supported) and Ogg Vorbis
 files into smaller files without decoding. Useful for splitting albums, either

 This is the package you need to develop or compile applications that
use mp3splt.


Thanks for any help. I am a novice debian developer.

Thanks,
