>Description:
PkgSrc's version of mail/imap-uw (checked out via CVS on April 16th) bails out 
during compiling of osdep.c:

In file included from osdep.c:263:
/usr/include/openssl/x509v3.h:493: error: expected '=', ',', ';', 'asm' or 
'__attribute__' before '*' token
/usr/include/openssl/x509v3.h:493: error: expected ')' before '*' token

Output during the early stages of the compiling process confirms that indeed 
the in-tree version of OpenSSL gets included:

cd c-client;make neb EXTRACFLAGS='-O2 -I/usr/pkg/include' 
EXTRALDFLAGS='-L/usr/pkg/lib -Wl,-R/usr/pkg/lib' EXTRADRIVERS='mbox' 
EXTRAAUTHENTICATORS='' PASSWDTYPE=pam SSLTYPE=unix IP=6 
SSLINCLUDE=/usr/include/openssl SSLLIB=/usr/lib SSLCERTS=/etc/openssl/certs 
SSLKEYS=/etc/openssl/private GSSINCLUDE=/usr/include GSSLIB=/usr/lib 
PAMLDFLAGS=-lpam SSLDIR=/usr/pkg SSLCERTS=/usr/pkg/etc/openssl/certs 
SSLKEYS=/usr/pkg/etc/openssl/private CREATEPROTO=unixproto

A quick look at work/imap-2007e/Makefile reveals the reason: Even though 
PREFER_NATIVE is set to NO in /etc/mk.conf, the neb defines the following:

SPECIALS="SSLINCLUDE=/usr/include/openssl SSLLIB=/usr/lib 
SSLCERTS=/etc/openssl/certs SSLKEYS=/etc/openssl/private
>How-To-Repeat:
cd /usr/pkgsrc/mail/imap-uw && make update
>Fix:
Change the contents of the neb section in the main Makefile depending on 
PREFER_NATIVE in /etc/mk.conf ... I simply edited the Makefile by hand & 
imap-uw would compile without any problems afterwards.
