Josh,

I've never had any issue with it using the system installed wx
libraries on 10.5 or 10.6. Reading through the ticket, the library you
want to check for linkage is probably
$PREFIX/lib/erlang/lib/wx-0.98.1/priv/i386-apple-darwin9.6.0/wxe_driver.so.

For instance:

$ otool -L /usr/local/lib/erlang/lib/wx-0.98.1/priv/i386-apple-darwin9.6.0/wxe_driver.so
/usr/local/lib/erlang/lib/wx-0.98.1/priv/i386-apple-darwin9.6.0/wxe_driver.so:
	/System/Library/Frameworks/OpenGL.framework/Versions/A/OpenGL
(compatibility version 1.0.0, current version 1.0.0)
	/System/Library/Frameworks/QuickTime.framework/Versions/A/QuickTime
(compatibility version 1.0.0, current version 1290.0.0)
	/System/Library/Frameworks/IOKit.framework/Versions/A/IOKit
(compatibility version 1.0.0, current version 275.0.0)
	/System/Library/Frameworks/Carbon.framework/Versions/A/Carbon
(compatibility version 2.0.0, current version 136.0.0)
	/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa
(compatibility version 1.0.0, current version 12.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
version 111.1.3)
	/usr/lib/libwx_macud_stc-2.8.0.dylib (compatibility version 2.6.0,
current version 2.8.4)
	/usr/lib/libwx_macud-2.8.0.dylib (compatibility version 2.6.0,
current version 2.8.4)
	/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.4.0)
	/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)

Granted, that's not the same as disabling the whole thing altogether.

HTH,
