I stopped the build and continued by starting
another . . .
Without both -J and ALLOW_MAKE_JOBS ((so implicitly
-J4 in the context) it got the following results
for the 4-left of 5 originally failing:
[00:00:51] [02] [00:00:19] Finished textproc/itstool | itstool-2.0.6: Failed: configure
[00:05:00] [02] [00:02:38] Finished x11-toolkits/libXaw | libXaw-1.0.13_3,2: Success
[00:19:02] [03] [00:15:00] Finished devel/gdb@py37 | gdb-10.1_1: Failed: build
[00:29:33] [01] [00:29:01] Finished devel/cmake | cmake-3.19.6: Failed: configure
17 ports built that depend on textproc/libxslt and/or
x11-toolkits/libXaw . The 3 failures above made the
rest (100) skip.
textproc/libxslt and x11-toolkits/libXaw sometimes failing
and sometimes not suggests a racy context at some level
of the operations involved.
