Error "Helmholtz EoS external functions not available"

Hi everyone. I installed the framework and decided to check if it worked correctly. To do this I ran the example "subcritical_boiler_src" (code below):

import os

# Import Pyomo libraries
import pyomo.environ as pyo
from pyomo.network import Arc

# Import IDAES core
from idaes.core import FlowsheetBlock
from idaes.core.util.model_statistics import degrees_of_freedom
from idaes.core.util import model_serializer as ms
import idaes.core.util.scaling as iscale

# Import Unit Model Modules
from idaes.models.properties import iapws95

# Import IDAES standard unit model
import idaes.logger as idaeslog
from idaes.models_extra.power_generation.unit_models.drum import Drum
from idaes.models_extra.power_generation.unit_models.downcomer import Downcomer
from idaes.models_extra.power_generation.unit_models.waterwall_section import (
    WaterwallSection,
)
from idaes.models_extra.power_generation.properties.flue_gas_ideal import (
    FlueGasParameterBlock,
)

# import subcritical functions
import idaes.models_extra.power_generation.flowsheets.subcritical_power_plant.subcritical_boiler as sub

# Create a Concrete Model as the top level object
m = pyo.ConcreteModel()
# Add a flowsheet object to the model
m.fs = FlowsheetBlock(dynamic=False)
# Add property packages to flowsheet library
m.fs.prop_water = iapws95.Iapws95ParameterBlock()
m.fs.prop_gas = FlueGasParameterBlock()

# create drum, downcomer, waterwall section models and connections
sub.create_model(m)
# set inputs (equipment dimensions and inlet conditions)
sub.set_inputs(m)
# initialize each model at the time
sub.initialize(m, outlvl=0)

when I ran the code I got an error:

2024-01-24 17:22:48 [ERROR] idaes.core.base.process_block: Failure in build: fs.prop_water
Traceback (most recent call last):

    raise RuntimeError("Helmholtz EoS external functions not available")
RuntimeError: Helmholtz EoS external functions not available
ERROR: Constructing component 'fs.prop_water' from data=None failed:

I thought it was due to poor performance between versions pyomo and IDAES but attempts to install an older version led to the same result. Does anyone know how to solve this problem with functions Helmholtz.

IDAES / idaes-pse
