>Description:
In mk/buildlink3.mk and wrapper/arg-pp-main, there is a transformation
rule for DynaLoader.a -> libDynaLoader_pic.a and back, so that libtool
recognizes it as a shared object.
However, at least for gnumeric, the transformed argument is passed off
to ar(1), which doesn't find it (and caused a build failure in gnumeric
before I disabled the perl plugin there).
>How-To-Repeat:
cd /usr/pkgsrc/math/gnumeric
enable the perl/bl3.mk inclusion again.
On -current after 3.99.16, 'make'.
(before that the same error happens but is disregarded by
the build system somehow):

>Fix:
Either teach libtool to recognize shared objects differently,
or at least identify DynaLoader.a as shared, or add handling for
ar(1) arguments. Or some other way?
