[Click] undefined symbol in own package

[Bayani Carbone]

Hi, I've created my own package with my own elements. When I run click 
on my own machine (2.6.24) everything works fine. However, I'm trying to 
run click with my package on a Soekris box (2.6.19.2) . I get the 
following error:

click script.click
While loading package 'bam':
 package /.../lib/bam.uo: undefined symbol: 
_ZNK7Element13configurationER6VectorI6StringE
requirement 'bam' not available

I've installed click on the box and recompiled my package there too. I 
also included click/vector.hh in my .hh files and click/vector.cc in my 
.cc files.

Can anyone help?

Thank you,

Bayani
