postfix-2.7.1 build error when selecting variant dovecot_sasl

[Markus.Ueberall@…]

With changeset [68844], a number of "set CCARGS [concat ${CCARGS} ...]" blocks got replaced by the more elegant "lappend CCARGS ..." equivalent--however, the dovecot_sasl variant definition below is problematic:

variant dovecot_sasl description "add Dovecot SASL support " {
    lappend CCARGS  -DUSE_SASL_AUTH -DDEF_SERVER_SASL_TYPE=\\\\\\"dovecot\\\\\\"
}

According to the logfile, this becomes

:info:build /usr/bin/gcc-4.2 -DNO_PCRE -arch x86_64 -DUSE_TLS -DHAS_SSL -I/opt/local/include -DUSE_CYRUS_SASL -DUSE_SASL_AUTH -I/opt/local/include/sasl -DUSE_SASL_AUTH {-DDEF_SERVER_SASL_TYPE=\\\"dovecot\\\"} -DBIND_8_COMPAT -DNO_NETINFO -DRESOLVE_H_NEEDS_ARPA_NAMESER_COMPAT_H -DNO_KQUEUE -g -O2 -I. -DMACOSX -c alldig.c

Removing the numerous escape chars did the trick (cf. attached diff).

Portfile diff (removes escapes which prevented proper build for variant dovecot_sasl)

Thanks. Not sure why it was like that in the first place. r69582
