hi,

i've installed FreeBSD v6.2-RELEASE, plus 'portconf' & 'ccache' from ports.

i've setup,

 /etc/make.conf
 -----------------------------
 PERL_VER=5.8.8
 PERL_VERSION=5.8.8
 USE_OPENSSL_PORT=true
 OPENSSLBASE=/usr/local
 USE_OPENSSH_PORT=true
 WITHOUT_X11=yes
 CPUTYPE?=pentium-mmx

 CFLAGS=      -O2 -pipe
 COPTFLAGS=   -O2 -pipe

 ## 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

 .if !defined(NOCCACHE)
  CC=/usr/local/libexec/ccache/cc
  CXX=/usr/local/libexec/ccache/c++
  CPP=/usr/local/libexec/ccache/cpp
 .endif
 -----------------------------

so that i can turn OFF use of ccache for individual ports.

i find that different ports 'respond' only to specific ways of setting
the NOCCACHE var.

e.g., in,

 cat /usr/local/etc/ports.conf
 -----------------------------
 *:\
 CFLAGS= -O2 -pipe -funroll-loops -s -frename-registers
-fomit-frame-pointer | \
 CXXFLAGS= -O2 -pipe -funroll-loops -s -frename-registers

 databases/sqlite3-threads:NOCCACHE=true | \
   
WITHOUT_DEBUG=true|WITH_DOCS=true|WITH_FTS1=true|WITH_TCLWRAPPER=true|BATCH=Yes

 sysutils/pflogx:MAKE_ENV= NOCCACHE=true | \
   WITH_EXPAT=true|BATCH=Yes
 -----------------------------

pflogx and sqlite3 require DIFFERENT specifications of NOCCACHE ...
swapping formate, e.g., causes the conditional ".if
!defined(NOCCACHE)" to fail; meaning, that the CC/CXX/CPP defs
pointing to ccahce/* are oncorrectly used.

is this expected/normal?  i would've expected the same method of
defining ENV VAR knobs ...

is there a _consistent_ way of turning off NOCCACHE via the ports.conf?

thanks!
