Mobility GPS plugin -- Fail to load custom library

[Frameworks]

Hi,

I pulled the experimental branch (2011-06-09) but I still cannot load my 
testing GPS library:

./..
D/dalvikvm(  408): Trying to load lib 
/data/local/qt/plugins/platforms/android/libandroid-8.so 0x44ede2c0
D/dalvikvm(  408): Added shared lib 
/data/local/qt/plugins/platforms/android/libandroid-8.so 0x44ede2c0
I/Qt      (  408): qt start
*D/dalvikvm(  408): Trying to load lib 
/mnt/sdcard/Android/data/org.ilri.*/*/GPSTest/////libGPSInterface//.so 
0x44ede2c0
I/dalvikvm(  408): Unable to 
dlopen(/mnt/sdcard/Android/data/org.ilri.//GPSTest/////libGPSInterface//.so): 
Cannot load library: load_segments[907]: 33 failed to map segment from 
'//libGPSInterface/*/*.so' @ 0x81900000 (0x00003470). p_vaddr=0x00000000 
p_offset=0x00000000*
..../


I though It was because I was not defining the PRO in the right way.. 
Here is the pro that builds the library:

/# -------------------------------------------------
# Project created by QtCreator 2010-04-30T11:56:42
# -------------------------------------------------
QT += sql
TARGET = GPSInterface
CONFIG += qt plugin dll

TEMPLATE = lib

DEFINES = QT_STATICPLUGIN

SOURCES += \
     ../../interfaces.cpp
HEADERS += ../../interfaces.h
#DestDir is on my linux system then I copy the so into the virtual SD Card
DESTDIR = /mnt/sdcard/Android/data/org.ilri.GPSTest/

I added the code the tries to load my library into QTApplication.java 
just after loading the QT libraries:
/...
try
         {
             File str;
             String storage;
             str = Environment.getExternalStorageDirectory();
             storage = str.getAbsolutePath();

             File f = new 
File(storage+"/Android/data/org.ilri.GPSTest/libGPSInterface.so");
             if (f.exists())
                 
System.load(storage+"/Android/data/org.ilri.GPSTest/libGPSInterface.so");
         }
         catch (SecurityException e)
         {
             Log.i(QtTAG, "Security: Can't load libGPSInterface.so", e);
         }
         catch (UnsatisfiedLinkError e)
         {
             Log.i(QtTAG, "Link: Can't load libGPSInterface.so", e);
         }
.../

Any idea what do I need to do or doing wrong?

Many thanks,
Carlos.
