dpkg -l | grep fpc
ii  fpc 3.0.0+dfsg-2                                 all          Free 
Pascal - SDK suite dependency package
ii  fpc-3.0.0 3.0.0+dfsg-2                                 all          
Free Pascal - SDK-3.0.0 suite
ii  fpc-source 3.0.0+dfsg-2                                 all          
Free Pascal - SDK source code dependency package
ii  fpc-source-3.0.0 3.0.0+dfsg-2                                 
all          Free Pascal - SDK source code

This is consistent with:

fpc -v
Free Pascal Compiler version 3.0.0+dfsg-2 [2016/01/28] for x86_64

sudo dpkg -i fpc_3.0.4-rc1_amd64.deb
dpkg: regarding fpc_3.0.4-rc1_amd64.deb containing fpc:
  fpc conflicts with fpc
   fpc-3.0.0 provides fpc and is present and installed.

dpkg: error processing archive fpc_3.0.4-rc1_amd64.deb (--install):
  conflicting packages - not installing fpc
Errors were encountered while processing:

Unfortunately the gui installer did NOT produce any error messages so I 
was misled into thinking that it was successful.

This gives me enough information that I can continue.  I'll keep you 
informed of my progress.
