FreeBSD Port: octave-3.8.1_2

[Joseph Mingrone]

Hello,

Building octave on a laptop (i5/8G ram running 9.2-STABLE amd64) seems
to run indefinitely (e.g. overnight and it's still building), but on a
similarly configured desktop (9.2-STABLE 32G ram) it takes no time
(15-20 minutes).  Here is a log from the build on the laptop:
https://ftfl.ca/octave_3.8.1_2_build_log.txt.

Once the build is killed, the following is output:

mv -f corefcn/.deps/corefcn_libtex_parser_la-oct-tex-parser.Tpo corefcn/.deps/corefcn_libtex_parser_la-oct-tex-parser.Plo
mv: rename corefcn/.deps/corefcn_libtex_parser_la-oct-tex-parser.Tpo to corefcn/.deps/corefcn_libtex_parser_la-oct-tex-parser.Plo: No such file or directory
gmake[3]: *** [corefcn/corefcn_libtex_parser_la-oct-tex-parser.lo] Error 1
gmake[3]: Leaving directory `/wrkdirs/usr/ports/math/octave/work/octave-3.8.1/libinterp'
gmake[2]: *** [all] Error 2
Killed

I tried turning off tmpfs and setting vfs.zfs.arc_max to 500M, but it
didn't make any difference.
