Help building haiku?

hi
i don’t know what i’m doing wrong,but when i try to configure the source following this guide http://www.haiku-os.org/guides/building,i get this:

Welcome to the Haiku shell.

~> cd haiku/haiku/generated.x86gcc4
~/haiku/haiku/generated.x86gcc4> …/configure --alternative-gcc-output-dir …/generated.x86gcc2 --cross-tools-prefix /boot/develop/abi/x86/gcc4/tools/current/bin/
…/configure: line 382: cd: …/generated.x86gcc2: No such file or directory
~/haiku/haiku/generated.x86gcc4> cd …
~/haiku/haiku> cd haiku/haiku/generated.x86gcc2hybrid
bash: cd: haiku/haiku/generated.x86gcc2hybrid: No such file or directory
~/haiku/haiku> …/configure --alternative-gcc-output-dir …/generated.x86gcc4 --cross-tools-prefix /boot/develop/abi/x86/gcc2/tools/current/bin/
bash: …/configure: No such file or directory
~/haiku/haiku> cd …

although the folders exist in the right places i keep getting this msg.
