I also found that strange and did some more research.

In my FreeBSD laptop I see that the symbol is in libssl:

freebsd$ readelf -s /usr/lib/libssl.so|grep DTLSv1
   309: 000000000001d0c0     8 FUNC    GLOBAL DEFAULT   10
DTLSv1_server_method
   452: 00000000002511e0   104 OBJECT  GLOBAL DEFAULT   22 DTLSv1_enc_data
   454: 000000000001b820     8 FUNC    GLOBAL DEFAULT   10
DTLSv1_client_method
   567: 0000000000018410     8 FUNC    GLOBAL DEFAULT   10 DTLSv1_method


The problem seems to be that in the NetBSD virtual machine, it isn't:

netbsd$ readelf -s /usr/lib/libssl.so|grep DTLSv1
   376: 00000000000199f0     8 FUNC    GLOBAL DEFAULT   10
DTLSv1_server_method
   542: 0000000000263840   112 OBJECT  GLOBAL DEFAULT   24 DTLSv1_enc_data
   544: 000000000001bf30     8 FUNC    GLOBAL DEFAULT   10
DTLSv1_client_method
   406: 00000000000199f0     8 FUNC    GLOBAL DEFAULT   10
DTLSv1_server_method
   572: 0000000000263840   112 OBJECT  GLOBAL DEFAULT   24 DTLSv1_enc_data
   574: 000000000001bf30     8 FUNC    GLOBAL DEFAULT   10
DTLSv1_client_method


I also checked the nearby netbsd xen dom0 for it, and here's the result:
   376: 00000000000199f0     8 FUNC    GLOBAL DEFAULT   10
DTLSv1_server_method
   542: 0000000000263840   112 OBJECT  GLOBAL DEFAULT   24 DTLSv1_enc_data
   544: 000000000001bf30     8 FUNC    GLOBAL DEFAULT   10
DTLSv1_client_method
   406: 00000000000199f0     8 FUNC    GLOBAL DEFAULT   10
DTLSv1_server_method
   572: 0000000000263840   112 OBJECT  GLOBAL DEFAULT   24 DTLSv1_enc_data
   574: 000000000001bf30     8 FUNC    GLOBAL DEFAULT   10
DTLSv1_client_method



So the NetBSD 6.0-stable dom0 has the same issue as the VM running
6.0-release.

I have tried to recompile libssl, but nothing changed. Also recompiled
asterisk, no luck.

You say you're running -current. I suppose your libssl will have
DTLSv1_method as shown by readelf?
