Comment (by iEFdev):

 Can we reopen this?

 Ok, I think I've found what's causing this.

 I notice today when the new 3.01 updated arrived that I got the binary
 version (ie not built from source) and it worked fine. But, when building
 from source it always fails (not just `htop` – any port that uses
 `ncurses`).

 Started to look around a bit, and noticed some of the paths set in the
 different `*_autoconf.tcl` files were programs in `/usr/local` (even if
 `/usr/local` wasn't in `PATH` during install). So I rebuilt my MacPorts
 installation (bootstrap-mp + mp), with a minimal `PATH` and I also renamed
 `/usr/local{,.bak}` during install, so it wouldn't pick up ''anything''.

 It still failed, but when renaming `/usr/local` or `/usr/local/include` it
 will build successfully.

 So, I guess something in MP is looking for headers in `/usr/local`, even
 though the port is setup to use `/opt/local` for headers and libs - and
 everything in the logs, etc looks fine.

 Building with `-t` works!

 It's hiding the file from the build system.

 So:

 {{{
 sudo port -vst install htop         # Works √
 sudo port install htop              # Doesn't work
 }}}

 Is there any way to make port ''not'' look around for more headers?

 Or where is this done in base?
