#56866: pstoedit @3.73_1: conflict problems with MacTeX - build failure
 Reporter:  majoc-at-astro  |      Owner:  (none)
     Type:  defect          |     Status:  new
 Priority:  Normal          |  Milestone:
Component:  ports           |    Version:  2.5.3
 Keywords:  haspatch        |       Port:  pstoedit
 When MacTeX is prepended to `binpath` (using instructions I can't locate
 atm), this causes two related problems to `pstoedit` at build time.

 * There's a hard build-time dependency on `texlive-bin-extras` to make
  `latex2man` available.  MacPorts dutifully installs a full copy of
  then uses the copy of `latex2man` in MacTeX.  (In our builds, the
  texlive is stripped out at the end of business, but it contributes to
  time, and may distract other package builds.)

  '''Fix:''' use a `bin` dependency on `latex2man`, as attached.

 * Whichever `latex2man` is used, it's run with Perl from MacPorts (via the
  `!#/usr/bin/env perl` trick), which is stricter about regular expressions
  than the system version.  The copy of `latex2man` in MacTeX 2017 contains
  regexp which the newer Perl objects to, and the build of `pstoedit`
  :info:build latex2man -t ./pstoedit.trans -M pstoedit.tex pstoedit.1
  :info:build Unescaped left brace in regex is illegal here in regex;
 marked by <-- HERE in m/\\([a-zA-Z]+){([^}]*)}{ <-- HERE ([^}]*)}/ at
 /Library/TeX/texbin/latex2man line 1287.
  :info:build make[1]: *** [pstoedit.1] Error 255
  '''Fix:''' update to MacTeX 2018.

 Please find enclosed the obvious one-line fix to the Portfile, which
 avoids the redundant `texlive` installation when `latex2man` is available
 via MacTeX.
 (Admission: I've not tested the MacTeX-absent case.)
 I'm not at all sure whether to use a `note` statement to document the
 version compatibility problem and solution, or whether it'd be more
 appropriate to trap for this as a precondition; please advise.

 System details: macOS 10.11, 10.12, 10.13; latest compatible versions of
 Xcode for each.

 Thanks in advance.  Apologies as usual for formatting problems or other
 sins of omission or commission, in particular (in the absence of a
 `pstoedit` maintainer) not knowing who to CC this to.

 PS: Can someone point me to the documentation for prepending MacTeX to
 `binpath`, please?  That's the logical location for the compatibility
 warning, but my search-engine fu is saying only "foo" today.
