+On a tumbleweed system, "install X Y" was showing the error:
+
+pseudo: ENOSYS for 'fsetxattr'.
+
+which was being caused by dlsym() for that function returning NULL. This
+appears to be due to it finding an unresolved symbol in libacl for this
+symbol in libattr. It hasn't been resolved so its NULL. dlerror() returns
+nothing since this is a valid symbol entry, its just not the one we want.
+
+We can add the glibc version string for the symbol we actually want so we get
+that version rather than the libattr/libacl one.
+
+To quote libattr:
+"""
+ These dumb wrappers are for backwards compatibility only.
+ Actual syscall wrappers are long gone to libc.
+"""
+and they are simply wrappers around the libc version so our attaching
+to the libc versions should intercept any accesses via these too.
