gEDA-user: pcb-20091103 for Gentoo, working on ebuild

[Stefan Salewski <mail@xxxxxxxxxxxx>]

Two questions:

stefan@AMD64-X2 ~/pcb/pcb-20091103 $ ./configure --help |grep lpr
  --with-printer= 	  Specify the printer: lpr [default=lpr]
I think lpr is the only available choice, and I read that leaving this
option out gives us all available printers. So I think we should not
specify this option at all for gentoo ebuild. But what is the
usage/benefit of this option, it is only a placeholder for future?

We have  --enable-toporouter-output now.
It needs cairo. Is this true for lesstif HID too.

Two remarks:

--docdir="/usr/share/doc/pcb-20091103"
seems to generate an obsolete empty directory
/usr/share/pcb-20091103/

For gentoo we like to have examples and tutorials in the doc
directories, so gentoo developers employ these patches:
#       sed -i -e 's/example//' -e 's/tutorial//' -e 's/ win32//' Makefile.in || die "sed failed"
#       sed -i -e 's/DOC=doc/DOC="doc example tutorial"/' configure || die "sed failed"
#       sed -i -e 's/$(pkgdatadir)/$(docdir)/' {example,tutorial}/Makefile.in || die "sed failed"

And some warnings from gcc4.4.2 on AMD64:
