That may not be possible, cf

It seems that the tar spec handles only pathnames up to 100 characters,
so there's no portable way of handling longer ones.  However, there is
a workaround: if the unused subdirectory

	fptools/libraries/base/Text/ParserCombinators/Parsec/examples

is removed before tarring, the longest name will be 80 characters,
and Solaris tar will be happy.
