ruby on rails - Nokogiri Gem Error Mac OS X Snow Leopard -


i searched around stack overflow , read few web pages , tried out method nokogiri website macports , homebrew, still nothing.

 gem install nokogiri   error:  while executing gem ... (errno::eacces)  permission denied - /library/ruby/gems/1.8/gems/nokogiri-1.5.9/.autotest

so, had use sudo command see if install it.

sudo gem install nokogiri building native extensions.  take while... error:  error installing nokogiri: error: failed build gem native extension.  /system/library/frameworks/ruby.framework/versions/1.8/usr/bin/ruby extconf.rb checking libxml/parser.h... yes checking libxslt/xslt.h... yes checking libexslt/exslt.h... yes checking iconv_open() in iconv.h... no checking iconv_open() in -liconv... no checking iconv_open() in -liconv... no checking libiconv_open() in iconv.h... no checking libiconv_open() in -liconv... no checking libiconv_open() in -liconv... no ----- libiconv missing.  please visit  http://nokogiri.org/tutorials/installing_nokogiri.html installing dependencies. ----- *** extconf.rb failed *** not create makefile due reason, lack of necessary libraries and/or headers.  check mkmf.log file more details.  may need configuration options.  provided configuration options: --with-opt-dir --without-opt-dir --with-opt-include --without-opt-include=${opt-dir}/include --with-opt-lib --without-opt-lib=${opt-dir}/lib --with-make-prog --without-make-prog --srcdir=. --curdir --ruby=/system/library/frameworks/ruby.framework/versions/1.8/usr/bin/ruby --with-zlib-dir --without-zlib-dir --with-zlib-include --without-zlib-include=${zlib-dir}/include --with-zlib-lib --without-zlib-lib=${zlib-dir}/lib --with-iconv-dir --without-iconv-dir --with-iconv-include --without-iconv-include=${iconv-dir}/include --with-iconv-lib --without-iconv-lib=${iconv-dir}/lib --with-xml2-dir --without-xml2-dir --with-xml2-include --without-xml2-include=${xml2-dir}/include --with-xml2-lib --without-xml2-lib=${xml2-dir}/lib --with-xslt-dir --without-xslt-dir --with-xslt-include --without-xslt-include=${xslt-dir}/include --with-xslt-lib --without-xslt-lib=${xslt-dir}/lib --with-libxslt-config --without-libxslt-config --with-pkg-config --without-pkg-config --with-libxml-2.0-config --without-libxml-2.0-config --with-pkg-config --without-pkg-config --with-libiconv-config --without-libiconv-config --with-pkg-config --without-pkg-config --with-iconvlib --without-iconvlib --with-iconvlib --without-iconvlib --with-iconvlib --without-iconvlib --with-iconvlib --without-iconvlib    gem files remain installed in /library/ruby/gems/1.8/gems/nokogiri-1.5.9  inspection.  results logged /library/ruby/gems/1.8/gems/nokogiri-1.5.9/ext/nokogiri/gem_make.out

it looks libxml , libexslt included in mac working while libiconv isn't. give perspective, trying use rspec, had errors capybara, not possible because nokogiri not working.

thanks has suggestions. said, homebrew didn't work - , don't plan on re-installing os because installing rails 3 quite annoying in case.
