i have forced the plugin to use the correctly installed jpgraph library by commenting code in pages/config_edit.php:

#if ( plugin_config_get( 'eczlibrary' ) != config_get( 'plugin_MantisGraph_eczlibrary' ) ) {
#  plugin_config_set( 'eczlibrary',  config_get('plugin_MantisGraph_eczlibrary') );
#}

#if ( plugin_config_get( 'jpgraph_path' ) != config_get( 'plugin_MantisGraph_jpgraph_path' ) ) {
#  plugin_config_set( 'jpgraph_path',  config_get('plugin_MantisGraph_jpgraph_path') );
#}

and in core/gantt_api.php

#if ( plugin_config_get( 'eczlibrary' ) != config_get( 'plugin_MantisGraph_eczlibrary' ) ) {
#  plugin_config_set( 'eczlibrary',  config_get('plugin_MantisGraph_eczlibrary') );
#}
#if ( plugin_config_get( 'jpgraph_path' ) != config_get( 'plugin_MantisGraph_jpgraph_path' ) ) {
#  plugin_config_set( 'jpgraph_path',  config_get('plugin_MantisGraph_jpgraph_path') );
#}

and having set the plugin_GanttChart_eczlibrary value to 0 in the configuration report page.
don't know whats wrong with the plugin, but now i see gantt charts ;)
