Error: (vcom-11) Could not find work.const

Hi everybody!
I'm trying to simulate my design (created using ISE) but I found
several problems.
VHDL code was originally written under ISE 6.1, then I passed to ISE
8.1. It worked good until a translate error occurred, and then I was
unable to execute any translate operation.
So I created a new project, copying all .vhd files I needed. Now ISE
gives me no error, but under Modelsim (XE III/Starter 3.0d) the
following error occurs:

# -- Loading package std_logic_unsigned
# ** Error: (vcom-11) Could not find work.const.
# ** Error: TOP_test.vhw(25): Cannot find expanded name: work.const.
# ** Error: TOP_test.vhw(25): Unknown record element "const".
# -- Loading package textio
# -- Loading package std_logic_textio
# ** Error: TOP_test.vhw(29): VHDL Compiler exiting
# ** Error: C:/Modeltech_xe_starter/win32xoem/vcom failed.
# Error in macro ./TOP_test.ndo line 7
# C:/Modeltech_xe_starter/win32xoem/vcom failed.
# while executing
# "vcom -explicit -93 "TOP_test.vhw""

"TOP_test" is the name of .tbw file I wanna run;
"const" is the name of the VHDL package that contains all parameters I
need.

What can I do?

Thanks

Compile the package first?

Under ISE 8.1 I didn't find the way to do that; I can't even check
package sintax.

I seem to remember that ISE lets you specify what kind
of VHDL each file represents - design, testbench or package.
I assume that it handles packages correctly if you tell
it about them.

Alternatively, you could stop fooling around with ISE to drive
the simulator, and do it properly from the simulator command
line

vcom mypackage.vhd
vcom mydesign.vhd
vcom mytestbench.vhd
vsim testbench
