Error while compiling eda simulation library

Actually, I pulled up a Riviera Pro simulation I'm running(in Q15.0) and it's added this way:

vlog $USER_DEFINED_COMPILE_OPTIONS "$QUARTUS_INSTALL_DIR/eda/sim_lib/altera_lnsim.sv" -work altera_lnsim

So maybe as the message says of adding -v2k5. Seems strange. Just a guess.

And to totally confuse you, I did a search on altera_lnsim.v, and in a 13.1 version of the simulation section of the Quartus handbook, I found:

VCS and VCS MX Guidelines

The following guidelines apply to simulating Quartus II designs in the VCS or

VCS MX software:

■ Do not specify the -v option for altera_lnsim.sv because it defines a

systemverilog package.

■ Add -verilog and +verilog2001ext+.v options to make sure all .v files are

compiled as verilog 2001 files, and all other files are compiled as systemverilog

I know this is for a different simulator, but thought I'd mention it.
