PHP is slotted, so it's not too unusual for multiple versions to be |
| 8 |
installed at the same time. An "emerge --depclean" may later remove |
| 9 |
the older one. But this alone is no cause for alarm. |

No, you're right. Whichever one you've eselected (if you're using |
| 21 |
apache's mod_php) is the one that will be used, and not all of the |
| 22 |
options will work with every installed PHP application. It doesn't |
| 23 |
make a ton of sense, but PHP is relatively stable these days. So, uh, |
| 24 |
good luck. |

C-language extensions like pecl-imagick are compiled against PHP. The |
| 32 |
USE_PHP variable declares which versions they may be compiled |
| 33 |
against. Then the user-facing variable PHP_TARGETS says which ones you |
| 34 |
want. What you ultimately get is the intersection of USE_PHP and |
| 35 |
PHP_TARGETS. |
