+#required by app-text/happypackage-2.0, required by happypackage (argument) |
| 53 |

+emerge: there are no ebuilds built with USE flags to satisfy "app-text/feelings[test]". |
| 63 |
+!!! One of the following packages is required to complete your request: |
| 64 |
+- app-text/feelings-1.0.0 (Change USE: +test) |
| 65 |
+(dependency required by "app-text/happypackage-2.0" [ebuild]) |
| 66 |
+(dependency required by "happypackage" [argument]) |
| 67 |
+</pre> |
| 68 |
+ |
| 69 |
+<p> |
| 70 |
+Such warning or error occurs when you want to install a package which not only |
| 71 |
+depends on another package, but also requires that that package is built with a |
| 72 |
+particular USE flag (or set of USE flags). In the given example, the package |
| 73 |
+<c>app-text/feelings</c> needs to be built with <c>USE="test"</c>, but this USE |
| 74 |
+flag is not set on the system. |
| 75 |
+</p> |
| 76 |
+ |
| 77 |
+<p> |
| 78 |
+To resolve this, either add the requested USE flag to your global USE flags in |
| 79 |
+<path>/etc/make.conf</path>, or set it for the specific package in |
| 80 |
+<path>/etc/portage/package.use</path>. |
