title: ./configure not seeing/finding boost header files
body: <p>Trying to build gearman from the gearmand-0.33.tar.gz from Launchpad using bzr, on a Fedora 64 system.</p>
  
  <p>doing the ./configure by tiself, as well as using the "-with-boost=/usr/include" param generates warnings an errors as the configure process can't seem to find/locate the boost header files. </p>
  
  <p>we've removed/reinstalled the boost header files via "yum install boost*" as well</p>
  
  <p>Any pointers will be tried!</p>
  
  <p>Thanks</p>
