Internal error: mod_fcgid: can't get tmp dir

This error appears when I try to upload a file, even for small files (~80k).
Fresh install, a can't figure out where I should configure to fix this, google does not help.

The site works just fine, only the file uploading doesn't work.

I tried to force TMPDIR in php5.fcgi, SetENV in .htaccess, upload_tmp_dir in php.ini... I'm lost.
