Hello,

Thank you, that wat exactly what I was looking for (the OPTIONS
variable).

I suppose I should read the whole "bsd.port.mk" Makefile.

P.S.: the Porter's Handbook does not say anything about the "OPTIONS"
variable (at least I did not found it with grep "OPTIONS" * in the
document directory).

Best Regards,
Ale
