I suspect that something else has dragged in the gui part of glc - |
| 18 |
wxwindows IIRC. |

A global use flag like X has different effects on different packages. |
| 30 |
Ususally it affects whether or not an X gui is built. However the only |
| 31 |
wat to really tell is to read the ebuild. In this case: |
| 32 |
|
| 33 |
"RDEPEND="!static? ( |
| 34 |
${COMMON_DEPEND} |
| 35 |
X? ( || ( media-gfx/xloadimage media-gfx/xli ) ) |
| 36 |
) |
| 37 |
selinux? ( sec-policy/selinux-gnupg )"" |
| 38 |
|
| 39 |
This indicates that if the X flag is enabled, there will be a dependency on either media-glx/xloadimage or media-gfx/xli |
| 40 |
|
| 41 |
"econf \ |
| 42 |
[snip] |
| 43 |
$(use_enable X photo-viewers) \ |
| 44 |
[snip] |
| 45 |
|
| 46 |
${myconf} || die" |
| 47 |
|
| 48 |
This indicates that something called photo-viewers is enabled in gnupg |
| 49 |
if the X flag is present. What this does, i don't know (or care) and |
| 50 |
will leave it to you to discover. |

See above, look at the ebuilds. |
