glpk: +doc variant fails

[someuser12]

1) On Mac OS X 10.6.4 with MacPorts 1.9.1, building the documentation of glpk fails: there are 4 "missing $ inserted" errors when running texi2pdf on gmpl.texi . When compiling manually, it is enough to press enter to accept the 4 suggestions.

I don't understand how to fix this in a clean way, since the incriminated latex code (line 2757, $$ \left\{ \matrix{=\cr\leq\cr\geq\cr}\right\}b_0-a_0 $$) compiles when put in a LaTeX document.

However, I notice that the recent versions of glpk (at least 4.43 and 4.44) come with a precompiled gmpl.pdf, thus I suggest upgrading the port to, say, version 4.44 and skipping the compilation of gmpl.pdf.

2) Additionnally, there is a slight dependency problem. When compiling glpk.tex the LaTeX package xy.sty is used, but it's not provided by the texlive port nor one of its dependencies. One has to also install the texlive-pictures port.

I attach to this ticket an update proposal to the Portfile that solves both issues and upgrades the port to version 4.44.

Sorry, the syntax of the email address in Cc (the port maintainer's) is wrong. It should be lutz.horn -(:at:)- fastmail.fm but it seems I have no privilege to fix this. Can anybody fix it, please? Thanks.

Fixed with #29133 in r78218. I didn't understand why we were still depending on various texlive ports and trying to build the pdf from source if pre-generated pdfs are already included. So I removed the doc variant and those dependencies and steps, and just always installed the existing pdfs.
