Thanks for resurrecting julia!

I have two remarks:

• any reason to work on 1.0.3? The latest release is now 1.5.4, and 1.6.0 is now at -rc3;
• when using the external BLAS, you could set USES+= blaslapack:openblas

The port is actually 1.0.5, the latest release is indeed 1.5.4 but the LTS version is at 1.0.5. I haven't got time yet to port the latest version over but I figure I can bring the LTS version back first.
For BLAS, since the original port works well therefore I think I'd just keep it as is.

Could you change the OPENLIBM to SYSLIBM as default option?

kargl@ suggests that switching back to system libm as default (or just removing the openlibm knob) since there are some issues on i386 platform (https://github.com/JuliaMath/openlibm/issues/205, https://github.com/JuliaMath/openlibm/issues/206). And these issues have been fixed by system libm.

Not sure why we need this?

Perhaps we can bring JULIA_DEFAULT back also? (It has been removed in https://reviews.freebsd.org/R11:12ec26904cd2f3c9093d5b3f4b07c71f0dbf30b9)

Ah, I didn't discover that knob before. Let's use it.

Something wrong with USES=metaport?

This is badly ordered, order is EXTRACT/BUILD/LIB.

This is at the wrong place, should be way up.

This does not actually need to be guarded by the openblas option.

metaport implies NO_INSTALL, but we still need to install the symlink.
