64 | |
65 | We have a number of reasons to believe that this is a development |
66 | checkout and that you, the user, did not run `perl Makefile.PL` |
67 | before using this code. You absolutely _must_ perform this step, |
dc4600b2 |
68 | and ensure you have all required dependencies present. Not doing |
69 | so often results in a lot of wasted time for other contributors |
70 | trying to assit you with spurious "its broken!" problems. |

dc4600b2 |

74 | please report the situation to either the mailing list or to the |
75 | irc channel as described in |
