misspelt filename in libsdl_gfx-framework Portfile

[tow@…]

Diff as shown - the case of one letter in the filename was wrong, and as a result the unzip fails on a case-sensitive filesystem.

post-extract {

• system "cd ${worksrcpath} && pwd && unzip \"Other Builds/OSX-PB-Xcode.zip\""

+ system "cd ${worksrcpath} && pwd && unzip \"Other Builds/OSX-PB-XCode.zip\""

system "cd ${worksrcpath} && \

tar -xzvf \"Other Builds/OSX-PB.tgz\"; mv PB/English.lproj ."

}
