[Linux-NTFS-User] Is the "attr" package needed at runtime or only at build time?

[Nikos C. <re...@ar...>]

To build ntfs-3g, the attr package is needed (the one that provides the 
libattr.so library and attr/xattr.h header).  However, after building, 
is the library still needed?

In other words, is it a build-time only dependency or also a runtime 
dependency?  Because if I uninstall it (meaning that libattr.so* are 
also gone), ntfs-3g keeps functioning correctly.  Are the specific 
features in ntfs-3g that will not function anymore without this library?
