The build path is embedded in various binaries:

  
https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/pure-ftpd.html

  /usr/bin/pure-pw

  /build/1st/pure-ftpd-1.0.50/src/alt_arc4random.c:149
  vs.
  /build/2/pure-ftpd-1.0.50/2nd/src/alt_arc4random.c:149

The attached patch fixes this in debian/rules by passing
-ffile-prefix-map in in CFLAGS.

With this patch applied pure-ftpd should build reproducibly on
tests.reproducible-builds.org!

Thanks for maintaining pure-ftpd!

live well,
