You may also find the attached patch helpful to cut down on compiler chatter
(though I think 'tar' will still build without it). I installed this as well.

Subject: [PATCH] tar: port xattr-at.c to Solaris 10
* lib/xattr-at.c (setxattrat, lsetxattrat, getxattrat, lgetxattrat)
(listxattrat, llistxattrat): Compile only if HAVE_XATTRS, so that
the code doesn't call functions that are not declared.
