Thanks, I suppose that was rather obvious! And it did allow the build to 
complete.

Trouble is, the result is version 2.5 and the whole thing about 2.5 is 
that it doesn't work. It crashes on every incoming email, with log 
entries like:

2020-10-29 07:11:21 #328643(rspamd_proxy) rspamd_crash_sig_handler: 
caught fatal signal 11(Segmentation fault), pid: 328643, trace:
2020-10-29 07:11:21 #328643(rspamd_proxy) rspamd_print_crash: 0: 
0000FFFF9F8AFC18: <unknown>
2020-10-29 07:11:21 #328643(rspamd_proxy) rspamd_print_crash: 1: 
0000000000000032: <unknown>

So it seems that the only conclusion must be that rspamd is not really 
available for arm at all. Although it has been included in the Ubuntu 
20.10 release (the specific Raspberry Pi download) it just does not 
work, and is not supported. Really very frustrating.

Installing from the Ubuntu repo was where I started. The rspamd from 
there does not work, it fails as above.
