 Priority:  Normal               |  Milestone:
Component:  base                 |    Version:  2.3.3

---------------------------------+--------------------------------
 Seems like a simple enough fix for anyone who is familiar with TCL and the
 base plumbing. I'm not unfortunately.

 Consider the following:
 {{{
 PortSystem          1.0
 name                backslash-test
 version             1
 categories          devel
 platforms           darwin
 description         tests backslashes in filenames for the activate target

 fetch               {}
 checksum            {}
 use_configure       no
 build               {}
 destroot {
     touch "${destroot}${prefix}/share/back\\slash"
 }
 }}}

 Which produces the following results
 {{{

 --->  Extracting backslash-test
 --->  Configuring backslash-test

 I've attached a full log of an install of the above portfile from a clean
 state.
