Planner-list libcairo-2.dll problem

I found a problem with Planner / libcairo-2.dll interface. The version 
installed using the directions off the website does not work. (I'm using 
cario-1.6.4-2.zip and cairo-dev-1.6.4-2.zip) The filesize for this 
version is: 621KB (636,570 bytes). When using this version, the svn 
built Planner app will crap out with the following error message : "The 
procedure entry point cairo_show_text_glyphs could not be located in the 
dynamic link library libcairo-2.dll"

If I use the version supplied with 
gtk2-runtime-2.14.6-2008-12-17-ash.exe, Planner works. The filesize for 
this version is: 763KB (781,961 bytes).

Other than that, Planner seems to run ok.
