           Summary: wireshark link fails on systems with no TLS library but
                    with grypt library (missing -lgrcyprt)
           Product: Wireshark
           Version: SVN
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: Medium
         Component: Wireshark
        AssignedTo: wireshark-bugs@xxxxxxxxxxxxx
        ReportedBy: jeff.morriss@xxxxxxxxxxx


As reported here:

http://www.wireshark.org/lists/wireshark-dev/200607/msg00018.html

links fail on systems that do not have the TLS library but do have the gcrypt
library (which is automatically picked up by 'configure'):

~~~
