<pre>On OS X systems (in my case, OS X 10.9.4), if the cache folder is on a mounted
network share (e.g. because the user's home directory is on an SMB or AFP
server), running fc-cache will fail to write to ~/.cache/fontconfig. This means
the lengthy caching process is performed every time fontconfig is used.
The issue can be fixed by applying the patch below as evidently, OS X returns
ENOTSUP when link() is performed on a file system that does not support
hardlinks instead of EPERM.
The issue occurs in fontconfig 2.10 and 2.11, possibly older ones as well.
