Linux installation failed cannot create directory

I did a download and install of matlab using sudo ./install from the downloader folder. I picked the usr/bin directory for install instead of usr/local/bin, with symbiolic links in usr/local/bin otherwise used defaults for everything.

It downloaded everything to a temp directory (8GB total) and began to install MATLAB itself (not the accessories) but failed with a strange error that could not resolve. The error box claimed that a .so file (/usr/bin/java/jarext/sqlite4java/libsqlite4java-linux-amd64.so) was not a directory. The error log claimed that it could not create the directory usr/local/matlab which is very strange since this error did not match the error in the popup box. I think there may be a bug which is putting the wrong text into the directory creation dialog. I attached the error logs.

I may be able to fix this if I can reset the install back to usr/local/bin or else create the usr/local/matlab myself prior to install.

Is there any way I can install from the temp directory files, It took 2 days to download the files, and I would not like to do that again. So far I have seen no install script in the downloaded files that doesn't require re-downloading everything I already downloaded.

PS: I renamed the log files as text files, because you have disallowed the attachment of log files. Seriously!? you guys disallowed attaching log files in a help/answers forum???
