gap_package installation doesn't respect alternate sage root

[Watson Ladd]

Dear all,

I am on Mac OS X and have installed sage to an alternate directory. However, when I run sage -i gap_package I get the following output:

sage -i gap_packages

You are using OS X Lion (or later).

You are strongly advised to install Apple's latest Xcode

unless you already have it. You can install this using

the App Store. Also, make sure you install Xcode's

Command Line Tools -- see Sage's README.txt.

configure: error: "found MacPorts in /opt/local/bin/port. Either:

(1) rename /opt/local and /sw, or

(2) change PATH and DYLD_LIBRARY_PATH

(Once Sage is built, you can restore them.)

If you would like to try to build Sage anyway (to help porting),

export the variable 'SAGE_PORT' to something non-empty.

make[1]: *** [build/make/Makefile] Error 1

make: *** [all-toolchain] Error 2

This doesn't seem to be the right thing, as sage is sitting elsewhere in the directory tree. Is there some magic option I overlooked to get this to work?

Sincerely,

Watson Ladd

Which one of the following options do you have problems with?

found MacPorts in /opt/local/bin/port. Either:

(1) rename /opt/local and /sw, or

(2) change PATH and DYLD_LIBRARY_PATH

(Once Sage is built, you can restore them.)

If you would like to try to build Sage anyway (to help porting),

export the variable 'SAGE_PORT' to something non-empty.
