157 | !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! |
158 | |
159 | We have a number of reasons to believe that this is a development |
160 | checkout and that you, the user, did not run `perl Makefile.PL` |
161 | before using this code. You absolutely _must_ perform this step, |
0424d17a |
162 | to ensure you have all required dependencies present. Not doing |
dc4600b2 |
163 | so often results in a lot of wasted time for other contributors |
23b2c49b |
164 | trying to assist you with spurious "its broken!" problems. |
ab340f7f |
165 | |
6e22e629 |
166 | By default DBICs Makefile.PL turns all optional dependencies into |
0424d17a |
167 | *HARD REQUIREMENTS*, in order to make sure that the entire test |
168 | suite is executed, and no tests are skipped due to missing modules. |
169 | If you for some reason need to disable this behavior - supply the |
170 | --skip_author_deps option when running perl Makefile.PL |
171 | |
