Given following log snippets, their explanation, and nothing else, explain what failure, if any, occurred during build of this package.

  Snippets are in a format of [X] : [Y], where [X] is a log snippet, and [Y] is the explanation.

  Snippets are delimited with '================'.

  Drawing on information from all snippets, provide a concise explanation of the issue and recommend a solution.

  Explanation of the issue, and recommended solution, should take a handful of sentences.

  Snippets:

  [ERROR:  Error installing ./bindings/ruby/openwsman-2.8.1.gem:
	ERROR: Failed to build gem native extension.]: [It show the main reason why the build failed.]
=============
[checking for wsman_create_doc() in -lwsman... no
Cannot find wsman_create_doc() in libwsman
Is openwsman-devel installed ?
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.]: [It shows more detailed info about build failure.]

Issue: The build failed due to fail to build gem native extension. When building gem native extension the Makefile for it couldn't be created because of fail check for wsman_create_doc() function in libwsman library.
Resolution: Install required library prior the build (add it to BuildRequires of the spec file) or if it was built previously during the build of the package, make it available exporting the path to it through LIBRARY_PATH and LD_LIBRARY_PATH path variables prior gem native extension build.
