Error building GNUstep

[Luke Lollard <haihige%protonmail.ch@localhost>]

Hello, I'm following this documentation to install GNUstep on NetBSD
10.0:
https://mediawiki.gnustep.org/index.php/Platform:BSD#NetBSD

I've run into some issues along the way. The first was an error while
compiling the examples. I found something online that is essentially the
same error I ran into:
http://shadow.netbsd.org/pub/pkgsrc/packages/reports/HEAD/NetBSD-9.0-x86_64/20240615.1049/gnustep-examples-1.3.0nb28/build.log

For a short-term fix, I removed the lines in the makefile and PLIST for
the service example and md5Digest.app.

But now I'm stuck on ProjectCenter. For some reason it won't finish
`make package` and I'm not sure what to do at this point. This is where
I get stuck:

I'm very new to NetBSD and would love to learn how to fix this. Is this
because this is an old version of ProjectCenter (the latest is 0.7.0)?
