Maybe someone could help me diagnose the problem:
Whatever I try, I get errors.
For example, clicking on the "Graph" command of a vocabulary, or the "schema" tab in admin/content/types I get the following error:

Graphviz encountered an error while rendering to format cmapx:
Error: Could not find/open font<br />Error: Could not find/open font<br />Error: Could not find/open font<br />Error: Could not find/open font<br />Error: Could not find/open font<br />Error: Could not find/open font<br />Error: Could not find/open font<br />Error: Could not .....

The graph is generated however. Sometimes, I don't get the graph initially, but a similar error about png, jpg or gif format

Thanks for help

Googling "Could not find/open font" graphviz reveals that these are issues that Graphviz users may encounter. Please go through them first and let me know if they help.

Hurrah!

After much search and tries, the problem was the following. On my Gentoo box,

1) no fonts were installed, as this is not a requirement for most servers.
I followed this post
http://en.gentoo-wiki.com/wiki/X.Org/Fonts
emerge -av --noreplace freetype corefonts freefonts artwiz-aleczapka-en terminus-font ttf-bitstream-vera unifont dejavu
- adding "truetype" in make.conf
yet without going up to the point of installing Xorg

2) gd was compiled without fontconfig support. I added "fontconfig" in the USE variable in make.conf file and re-emerged
This post was the most helpful

Hope this will help someone...
