Probably yes. As far as I can tell, the only safe way to see what USE |
| 15 |
flags apply to a package is to either look in the ebuild, or do "eix |
| 16 |
package." (Mick beat me to it on finding that.) |

It looks like the list of local use flags mentioned on |
| 19 |
packages.gentoo.org come from the metadata.xml file in the package |
| 20 |
directory, and at least for this package, that does not actually |
| 21 |
include all the available flags. (X bzip2 corefonts cxx djvu fftw |
| 22 |
fontconfig fpx graphviz hdri heif jbig jpeg jpeg2k lcms lqr lzma opencl |
| 23 |
openexr openmp pango perl png postscript q32 q8 raw static-libs svg |
| 24 |
test tiff truetype webp wmf xml zlib) I haven't figured out where it |
| 25 |
gets the list of global flags it uses, unless it is somewhere under |
| 26 |
/usr/portage/metadata. It also looks like euse uses the info in the |
| 27 |
metadata file, so, for example, "euse -i jpeg" does NOT mention |
| 28 |
imagemagick. |
