# This depends on an installation of Matlab which pkgsrc does
# not have.  We should find a sane way to deal with this.  It is
# not clear if linux/solaris matlab users care to use pkgsrc
# to manage its installation or if it will always be installed
# outside of pkgsrc.

# In addition, mex-wcalc will not currently build correctly
# if you are using a non-native matlab (i.e. linux or solaris
# matlab on NetBSD).
#
# To get mex-wcalc to work under emulation you need to set up
# a cross-tool chain, build a libwcalc targeted to the same
# system as the matlab installation, and modify the mexopts.sh
# file in ${WRKSRC}/mex-wcalc to use this cross tool chain.
# Basically what it comes down to is you need to compile shared
# modules for the same os as the matlab binary.
