Building Perl 5.28.0 on OpenBSD 6.4 -current

[fishy]

Hello Fellows,

I'm trying to build Perl 5.28.0 on OpenBSD 6.4 -current (snapshot november 03, 2018) but with only 99.96% success.

That is because when testing I get:

Failed 1 test out of 2459, 99.96% okay.
        run/locale.t

Running ./perl harness on t/run/locale.t, I get:

$ cd src/perl-5.28.0
$ LD_LIBRARY_PATH=`pwd`; export LD_LIBRARY_PATH; cd t; ./perl harness 
+t/run/locale.t
run/locale.t .. 2/? # Failed test 8 - In setting complicated invalid L
+C_ALL, final individ category doesn't need a ';' at run/locale.t line
+ 482
#      got "65280"
# expected "0"
# Failed test 9 - In setting complicated valid LC_ALL, final individ c
+ategory doesn't need a ';' at run/locale.t line 491
#      got "65280"
# expected "0"
run/locale.t .. Failed 2/9 subtests
        (less 1 skipped subtest: 6 okay)

Test Summary Report
-------------------
run/locale.t (Wstat: 0 Tests: 9 Failed: 2)
  Failed tests:  8-9
Files=1, Tests=9,  1 wallclock secs ( 0.02 usr  0.02 sys +  0.28 cusr 
+ 0.20 csys =  0.52 CPU)
Result: FAIL

Following the "make test" section of the INSTALL document (in perl source code), I tried without success the setting:

LC_ALL=C;export LC_ALL

Then I found this post where Karl Williamson wrote:

"locale tests can fail for a number of reasons. There could be a bug in
perl; there could be a bug in the platform; there could be a bug in a
particular locale definition."

Finally I digged deeper into the web and found following related tickets:
RT 122296 (year 2014)
RT 129953 (year 2016)

Now I'm confused and want to ask for some enlightenment.
I could install Perl and there will be no problem at all, maybe.

Just in case, my Configure arguments:

config_args='-des -Dprefix=/home/puffy/opt/perl-5.28 -Dman1dir=none -D
+man3dir=none -Dsite1dir=none -Dsite3dir=none -Dvendorman1=none -Dvend
+orman3=none'

Thanks and greetings.
