The problem now is in deps/blastrampoline.mk. This fetches and
compiles https://github.com/JuliaLinearAlgebra/libblastrampoline.git
as you can see in line 5 of deps/blastrampoline.mk.

What I do:

	git clone https://github.com/JuliaLinearAlgebra/libblastrampoline.git
	cd libblastrampoline/src
	gmake

This gives me the following error:

	libblastrampoline/src % gmake
	cc -o build/libblastrampoline.o -g -O2 -std=gnu99 -fPIC -DLIBRARY_EXPORTS -D_GNU_SOURCE -DARCH_x86_64 -DF2C_AUTODETECTION -DCBLAS_DIVERGENCE_AUTODETECTION -DCOMPLEX_RETSTYLE_AUTODETECTION -c libblastrampoline.c
	libblastrampoline.c: In function 'init':
	libblastrampoline.c:514:23: error: 'PATH_MAX' undeclared (first use in this function); did you mean 'RAND_MAX'?
		 char curr_lib[PATH_MAX];
			       ^~~~~~~~
			       RAND_MAX
	libblastrampoline.c:514:23: note: each undeclared identifier is reported only once for each function it appears in


Look at src/libblastrampoline_internal.h. There you'll find

	#if defined(_OS_FREEBSD_) || defined(_OS_OPENBSD_)
	...

You need to patch the following files:

	diff --git a/src/libblastrampoline.h b/src/libblastrampoline.h
	index 250e82b..1ca4739 100644
	--- a/src/libblastrampoline.h
	+++ b/src/libblastrampoline.h
	@@ -7,6 +7,8 @@ extern "C" {
	 // This shamelessly stolen from https://github.com/JuliaLang/julia/blob/master/src/support/platform.h

	+#define _OS_DRAGONFLY_

	 #elif defined(__linux__)
	diff --git a/src/libblastrampoline_internal.h b/src/libblastrampoline_internal.h

	 #include <dlfcn.h>

	-#if defined(_OS_FREEBSD_) || defined(_OS_OPENBSD_)
	+#if defined(_OS_FREEBSD_) || defined(_OS_OPENBSD_) || defined(_OS_DRAGONFLY_)
	 #include <stddef.h>

Then it compiles fine. Feel free to submit a Pull request (PR) to
JuliaLinearAlgebra/libblastrampoline.git with above changes.
