Homebrew and Permission denied issue - macos

Question

I try to compile and install libapreq2 via Homebrew package manager.
brew create http://www.apache.si//httpd/libapreq/libapreq2-2.13.tar.gz
The content of the libapreq2.rb formula is as follows.
require 'formula'
class Libapreq2 < Formula
url 'http://www.apache.si//httpd/libapreq/libapreq2-2.13.tar.gz'
homepage ''
md5 'c11fb0861aa84dcc6cd0f0798b045eee'
# depends_on 'cmake'
def install
system "./configure", "--disable-debug", "--disable-dependency-tracking",
"--prefix=#{prefix}"
# system "cmake . #{std_cmake_parameters}"
system "make install"
end
end
I proceed with
brew install -vd libapreq2
but unfortunately the compilation ended with errors.
mkdir: /usr/include/apache2/apreq2: Permission denied
make[3]: *** [install-pkgincludeHEADERS] Error 1
make[3]: *** Waiting for unfinished jobs....
/usr/bin/install -c .libs/mod_apreq2.so /usr/libexec/apache2/mod_apreq2.so
install: /usr/libexec/apache2/mod_apreq2.so: Permission denied

make[2]: *** [install-am] Error 2

make: *** [install-recursive] Error 1
Brew try to install some files outside the /usr/local/Cellar/libapreq2/ directory. I wonder how to manage these "permission denied" issues. I tried as root user (i.e., sudo brew install libapreq2), but if I later want to remove the library, only the files in /usr/local/Cellar/libapreq2/ are removed.
Thanks for any pointers.

Try this:
sudo chown -R $(whoami) /usr/local/Cellar/libapreq2/
It works for me!

Your package really shouldn't install anything in the system includes in /usr/include. The place for homebrew packaged includes is /usr/local/include (as symlinks into Cellar). You'll just have to adjust your ./configure invocation to use #{prefix}/include for the includes (probably --incdir or something very similar).
