undefined reference to symbol / ..libdl.so.2: error adding symbols: DSO missing from command line

Question

I currently have a problem compiling with gitian-builder.

It tells me this:

/usr/bin/ld: /usr/lib/x86_64-linux-gnu/libcrypto.a(dso_dlfcn.o): undefined reference to symbol 'dlclose@@GLIBC_2.2.5'
//lib/x86_64-linux-gnu/libdl.so.2: error adding symbols: DSO missing from command line

Does anyone know how to fix this?

I don't find anything useful.

Many thanks in advance!
