I understood that APR 0.9 has this 2-GB limitation, and that APR 1.0
does not. And that if you want to move from APR 0.9 to 1.0, you
should dump your repositories first and reload after. Of course, for
you, since you don't have any repositories yet, you can forget that

Since you're in a time crunch, maybe, I just hate workarounds. Seems
like it would be better in the long run to figure out why it's acting
this way and if there's a way to fix it. But if it's only the APR 0.9
2-GB revision-size limit, then this workaround (importing in smaller
chunks) should work and be safe.
