Link error when launching pgAdmin3 1.8 beta

I am running this on an updated Ubuntu Feisty with the following
wxWidgets installation:

jason(at)bunny ~/d/pgadmin3-1.8.0-beta1> wx-config --list

Default config is gtk2-unicode-release-2.8

Default config will be used for output

Alternate matches:
base-unicode-debug-2.8
base-unicode-release-2.8
gtk2-unicode-debug-2.8

jason(at)bunny ~/d/pgadmin3-1.8.0-beta1> wx-config --version 2.8
2.8.1

When launching the new build, I get the following error message:

jason(at)bunny ~/d/pgadmin3-1.8.0-beta1> /opt/pgadmin3/bin/pgadmin3
/opt/pgadmin3/bin/pgadmin3: relocation error:
/opt/pgadmin3/bin/pgadmin3: symbol wxEVT_AUI_PANE_BUTTON, version
WXU_2.8 not defined in file libwx_gtk2u_aui-2.8.so.0 with link time
reference

The configure and compile steps completed with no visible warnings or
errors.
