[gentoo-user] xypic wants ruby?

[Jorge Almeida]

Please help me to understand this:

$  emerge -pv  dev-texlive/texlive-pictures

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild  N    ] app-admin/eselect-ruby-20091225  2 kB
[ebuild  N    ] dev-lang/ruby-1.8.7_p249  USE="berkdb gdbm ipv6 ssl
-debug -doc -emacs -examples -rubytests -socks5 -threads -tk -xemacs"
4,058 kB
[ebuild  N    ] dev-texlive/texlive-pictures-2008-r1  USE="-doc -source" 576 kB

Total: 3 packages (3 new), Size of downloads: 4,636 kB

I need dev-texlive/texlive-pictures because it seems that's what
provides xy-pic.  Why in Hell am I obliged to install ruby? I
currently have no use for it. I can't begin to imagine why this
particular programming language should  be a must... Nothing in the
use flags suggests a clue, for me anyway...

Probably because it installs a heck lot more than just xypic? The full
list gives

  asyfig autoarea bardiag cachepic combinedgraphics circuitikz curve
curve2e curves dcpic diagmac2 doc-pictex dottex dot2texi dratex eepic 
epspdf epspdfconversion fig4latex gnuplottex here hvfloat miniplot 
pb-diagram petri-nets pgf-soroban pgfopts pgfplots picinpar pict2e 
pictex pictex2 pinlabel pmgraph randbild schemabloc swimgraf texdraw 
tikz-inet tikz-qtree tikz-timing tkz-doc tkz-linknodes tkz-tab 
tufte-latex xypic collection-pictures

Ruby is a RDEPEND; if you are interested you certainly can try
Googling to find out which in the above list is the offender. One
that I recognize which requires a ruby runtime is the converter epspdf.

Cheers,
