There is a dependency of the external http-client module to the 
data-converters module:

FIND_PACKAGE(zorba_data-converters_module REQUIRED  HINTS 
${DATA_CONVERTERS_BUILD_DIR})

In addition to the http-client I think you need to check it out to

/Users/pjl/src/flwor/zorba/repo/bug-996593/zorba_modules

I just double checked and the query works on ubuntu 12.04. with the
data-converters module installed.

Title:
  http client throws error with no content-type header in http response

Status in Zorba - The XQuery Processor:
  Opinion

Bug description:
  in modules/com/zorba-xquery/www/modules/http-
  client.xq.src/http_response_parser.cpp the function
  HttpResponseParser::parse() throws an error if the response doesn't
  contain a content-type. In this case theCurrentCharset is "".

  the surprising part is that in the following code
  transcode::is_necessary("") returns true and an icu_streambuf is
  created internally with an empty charset:

  if ( transcode::is_necessary( theCurrentCharset.c_str() ) ) {
    lStream.reset(
      new transcode::stream<std::istream>(
        theCurrentCharset.c_str(), theStreamBuffer
      )
    );
  }

  in the constructor of the icu_streambuf (src/util/icu_streambuf.cpp)
  the following code throws the error:

  external_conv_( no_conv_ ? nullptr : create_conv( charset ) )

  the correct behavior would be if the http-client would not throw an
  error if the content-type header is missing.
