Sorry for asking: but without a source change to the previous submitted revision:

what makes you believe it now builds?

it won't - and it can't

Maybe you should setup your devel project accordingly to SHOW you the error in the devel project. For one, you don't build the cyrus-sals-bdb flavor there (osc linkpac network cyrus-sasl network cyrus-sasl-bdb would help you show the issue)

The issue is rather simple: you have a dangling symlink of libsasl2.so to libsasl.so.3

libsasl2 is built as part of the MAIN package; the build script even explicitly rm -f libsasl2.so.3* (line 215 of cyrus-sasl-bdb.spec)

currently, there are two spec files that would be producing libsasl2-3: this is a no-go. only one package must produce the binary name at any given time.
