Comment (by javucho1000@…):

 I don't have access to any machine running 10.6 but, as suggested, adding
 {{{-std=c99}}} in the Makefile seems to fix the problem.

 This have been changed here:
 https://github.com/user454322/realpath/commit/1358f37ba759524c9c49225ad3b5aa3f314da6c3


 What would be the best approach to incorporate this fix into MacPorts?
