gnupg-1.9.20* has no dep listing for curl, has no compile options, but still attempts to link against curl. The pain of it is, it links against libcurl.so.2 - but I don't have libcurl.so.2, i have libcurl.so.3, so gpg is completely broken. gpg: error while loading shared libraries: libcurl.so.2: cannot open shared object file: No such file or directory ls /usr/lib/libcurl.so* /usr/lib/libcurl.so /usr/lib/libcurl.so.3 /usr/lib/libcurl.so.3.0.0
ET_EXEC libcurl.so.3,libc.so.6 /usr/libexec/gnupg/gpgkeys_hkp ET_EXEC libcurl.so.3,libc.so.6 /usr/libexec/gnupg/gpgkeys_curl only those two files dep on curl for me, and those belong to gnupg-1.4. Gnupg-1.4 has a curl dep. revdep-rebuild helps for soname changes. I recursively grepped the gnupg-1.9.20 archive for curl but cannot find anything. Please reopen if you have more information.

Uhm this is 1.4.x executable and a revdep-rebuild should help with it.
