Problem with Fragments

hi,
I am running the latest version of avogadro on ubuntu 10.04, amd 64bit.

when I try to insert any “fragment” i got the message:

Cannot read file format of file
/usr/local/share/avogadro/fragments/yyyy/xxxx.cml.

where yyyy is the directory and xxxx is the name of the molecule to insert.

how can i fix it?

thank.

when I try to insert any “fragment” i got the message:
Cannot read file format of file /usr/local/share/avogadro/fragments/yyyy/xxxx.cml.

Usually, this means that Open Babel was compiled without libxml2 support, so the XML file formats (like CML) don’t work.

If you try File->Open that file, does it work?

Cheers,
