Looking at https://github.com/libarchive/libarchive/blob/master/configure.ac 
it looks like many of these dependencies are configurable and hardly necessary 
for uncompressing zip files. It might make sense to try rebuilding libarchive 
using "--without-xml2 --without-nettle --without-bz2lib --without-lzo2
--without-lzma --without-iconv --without-zlib" and see if it makes a 
difference.
