Since I am working on Macs I wrapped libcurl with a cocoa object.

- (id) initWithUser:(NSString *) aUserName pass: (NSString *)
aPassWord host: (NSString *)aHostName dir: (NSString *) aDirName
textMode:(BOOL)asText{
    if (self = [super init]){
        userName = [aUserName copy];
        passWord = [aPassWord copy];
        hostName = [aHostName copy];
        dirName = [aDirName copy];
        curlHandle = curl_easy_init();
        curl_easy_setopt(curlHandle, CURLOPT_UPLOAD, TRUE);
        curl_easy_setopt(curlHandle, CURLOPT_FTP_RESPONSE_TIMEOUT, 25);
        curl_easy_setopt(curlHandle, CURLOPT_FORBID_REUSE, TRUE);
//fixes problem with server attempting to reset dir.
        curl_easy_setopt(curlHandle, CURLOPT_TRANSFERTEXT, asText);
    }
    return self;
}

and the send...

- (NSString *) sendFile: (NSString *) aFile{

    CURLcode anErr;
    FILE * filePtr;
    const char * cFile = [aFile cString];
    curl_easy_setopt(curlHandle, CURLOPT_USERPWD, [[NSString
stringWithFormat:@"%@:%@",userName,passWord] UTF8String]);
    NSString * verURL = [NSString
stringWithFormat:@"ftp://%@/%@/%@",hostName, dirName,[aFile
lastPathComponent]];

    filePtr = fopen (cFile, "r+");

    curl_easy_setopt(curlHandle, CURLOPT_URL, [verURL cString]);
    curl_easy_setopt(curlHandle, CURLOPT_READDATA, filePtr);
// curl_easy_setopt(curlHandle, CURLOPT_VERBOSE, YES);

    anErr = curl_easy_perform(curlHandle);

    fclose (filePtr);

    if (anErr) return [NSString stringWithFormat:@"Error in sendFile:
%d,file: %@ host: %@", anErr, aFile, hostName];
    return NULL;
}

Thank you again for your help on this. It's frustrating to me that
identical systems either work or don't work.
