EDIT: Got it! Still need to make sure there won't be unexpected bugs but it seems to be working, thus far.
ORIGINAL:
Or, in other words, I could use some help.
I'm not terribly familiar with make and associated tools but I have this, so far:

(license license:bsd-3))) The build has a lot of external libraries it tries to download so I tried adjusting the configure so they would skip getting build but still provide them as inputs; I may need to handle that differently or there may be flags I could, instead, pass rather than editing the files directly but I was just trying to get something to build, for starters.
If you try installing the file, you'll find that a second configure file causes things to fail; the issue is that configure.ac generates compile, config.guess, config.sub, install-sh, and missing and, I assume, the second configure script but it does so with #!/bin/sh, rather than with the bash that Guix is using.
Since these scripts get generated by configure.ac – after the GNU build system has finished updating all locations of #!/bin/sh –, it also means that it's in the middle of the configure phase, as part of when src/configure is being run: so I don't know how to update it, any. I'd…imagine(?) there's a way to set what shebang is used for these generated scripts but, like I mentioned, I'm unfamiliar with the tooling and wasn't able to figure it out.
Also – in case anyone knows or wants to help –, I'll put the log results here, in case there's anything that'd be helpful that I might miss in my unfamiliarity. It's just the configure portion as my computer is having trouble copying the whole thing and Reddit's code block seems to be having trouble with formatting:
