misc/mc build failure with portconf installed

[andrew clarke]

Hi,

===>  Configuring for mc-4.7.0.1
configure: error: invalid variable name: +
===>  Script "configure" failed unexpectedly.

I tracked this error down to some settings portconf-1.4 adds to
/etc/make.conf:

# Begin portconf settings
# Do not touch these lines
.if !empty(.CURDIR:M/usr/ports*) && exists(/usr/local/libexec/portconf)
_PORTCONF!=/usr/local/libexec/portconf
.for i in ${_PORTCONF:S/|/ /g}
${i:S/%/ /g}
.endfor
.endif
# End portconf settings

Once I uninstall portconf, which removes the above lines from make.conf,
mc builds normally.

Regards
Andrew
